I experienced this too on mac osx 10.6.6, repository version (2.0.9) spyderlib, PyQt4 4.8.3. Same results with spyder -d. Got spyder back to work by deleting the .spyder2 directory in user dir. 

Hi,

Does the solution provided by Petrush work for you? Unfortunately most of the main devs don't have a Mac to test Spyder.

Cheers,
Carlos

Sorry, I was out of office and did not have the time to test the suggestion.
I will try it soon, and report back.

Imri

Thanks Imri and please don't forget to update to the latest version of Spyder

I deleting ~/.spyder2 but Spyder continues to crash.

(I've downloaded and reinstalled the latest version of spyder and all its dependencies.)

Is this a Spyder issue? can it be a pyqt issue? or a qt issue?
Is there a way I could get more debug information from spyder to help fix this bug? I tried the -d flag, which you can see at the original bug report, but the output does not look very informative to me.

It seems this is an OS X related problem. See  Issue 502  for other strange problems that occur only on a Mac.

My guess is that this is a PyQt or/and a Qt problem. If you want to get a bit more info, you can go to the View menu and select "Internal console". This is the place where all internal error messages go. Try to look at what gets printed there before spyder crashes, or even better, record a video of your desktop during the process so that you can take a close look of that window.

If something gets printed on the internal console, please report back so we can do something about it.

thank you for your help.
I've opened the the internal console but nothing is printed there. 
Am I missing something?

Don't worry Imri, this means that the problem is not an spyder one (good to know), but a PyQt/Qt one.

I'll try to borrow a Mac's friend to check this out.

I also get this problem with spyder 2.0.11, Python 2.7.1, Qt 4.7.2, PyQt 4.8.3 on Mac OS X 10.6.6. The crash occurs when maximising or re-arranging the editor or console panes, but not the object inspector / variable explorer / etc one, which works fine. I think that  issue 673  is a duplicate of this one.

I had a similar crash (Segmentation fault). Click and drag the 'Console' window causes Spyder to crash. Details in the attached crash log. Also on OS X (10.6.7) with Spyder 2.0.12 and Python 2.6.6, Qt 4.7.1, PyQt 4.8.1

Same issue. Similar specs... any updates?

 Issue 673  has been merged into this issue.

Ok, this is clearly related to OS X only (so this is harder for me to debug unfortunately).

Anyway, here are some facts:
1. On Windows, rearranging dockwidgets works perfectly (no warnings, no segfault)
2. On Linux (Ubuntu 10.04 LTS), there are warnings in the console (see attached file) but no segfault, so it's acceptable

So, maybe preventing the warning display on Linux could prevent the segfault on OS X...

 Issue 725  has been merged into this issue.

This is almost certainly due to to the extra buttons that are being drawn in the tab-bar (time / options / kill the current process) -- the internal console happily re-/un-docks, as do the file explorer, and variable explorer, but any windows (not just consoles) with extra buttons in the tab-bar crash, probably because there is nowhere to draw them in a floating (tabless) window...  Perhaps they could go into an actual toolbar when these are un-docked?

I can confirm that only un-docking the editor and the console makes Spyder crash. There are no problems with the other plugins.

I also attach the crash report generated by the system (I can't read anything useful there but maybe it can help).

I discovered the problem after a quick glance at the Qt bug tracker. It's a bug in Qt itself. Check out these two bug reports:

https://bugreports.qt.nokia.com/browse/QTBUG-14365
https://bugreports.qt.nokia.com/browse/QTBUG-20104

The solution is not to enable documentMode in the QTabwidget of both the External Console and Editor plugins. I can confirm that commenting lines 329-330 and 565-566 of spyderlib/plugins/externalconsole.py and spyderlib/widgets/editor.py make the issue disappear.

From the documentation for DocumentMode

http://doc.qt.nokia.com/4.7-snapshot/qtabwidget.html#documentMode-prop

it seems like it wouldn't be a big deal to disable it on Mac to make this ugly bug go away.

This is a mac specific bug, it doesn't happen in linux. I haven't tried it
in Windows

Thanks Oren. Yes, this is a mac only bug, that's why we have assigned the OpSys-OSX label to it.

Implemented fix proposed in comment 20 in MacPorts r82602.

This issue was closed by revision 4e4ccecf9342.

Thanks all for your patience. We added a temporal fix until the mentioned Qt bug is fixed. It will be release with 2.1.
