What steps will reproduce the problem?
1. Start superswitcher
2. Use my computer
3. superswitcher missing

What is the expected output? What do you see instead?
I expect it to WORK more than a halb of a hour.
I see this when I start superswitcher from a terminal:
u-foka@u-foka-laptop:~$ superswitcher 

(superswitcher:8305): Wnck-CRITICAL **: wnck_workspace_get_number:
assertion `WNCK_IS_WORKSPACE (space)' failed
Segmentation fault (core dumped)

What version of the product are you using? On what operating system?
0.6, installed from deb package on ubuntu gutsy.

Please provide any additional information below.
I used the previous version of superswitcher before on feisty with no
problems, but the older version can't install on gutsy :S

superswitcher 0.6 segfaulted on me fairly quickly as well.  I open up about three
windows for each of four workspaces and it segfaulted shortly after closing one of
them.  I clicked on the window in the superswitcher menu before closing it (by
clicking the close button on the window's frame).

Which window manager are you guys using?  Metacity, compiz, or something else?
Comment 3 by phillip.c.warner, Mar 22, 2008
fluxbox 1.0.0
Slackware 12.0
libwnck-2.18.0

The segfault only happened to me once so far, but I only tried out the program for
about 30 minutes.

I've just committed revision 33, which should be more robust to things like window
managers that aren't Metacity.  If you can check out and build from the latest
source, let me know if this latest version helps fix the crashes you've been seeing.

Hey I think the randomness is caused by windows that have "Always on visible
workspace" option set - as commented here

Hi, I was using superswitcher 0.6 in Puppy Linux 214X (Release Candidate) and I had
the same segfault right after I killed any other running application.

Anyway after I installed the latest SVN version (Revision 37) I didn“t get any
segmentation fault in Puppy Linux, I can kill any app and superswitcher still works
fine without errors.  Puppy Linux uses JWM Windows Manager and Rox-Filer.

It seems that you get few feedback about the latest Revisions and this segafault
issue, In my opinion this is a mayor bug fixed in latest SVN. I suggest you to
Release in your HomePage a new version (could be 0.65 or something between) with the
latest SVN version, because few people try the latest SVN versions or search inside
the google.code pages and as I said before this is a mayor bug that prevents
Superswicther to be used in a wider range of Windos Managers.

Than your for the attention pleased.  

I also want to wish you a very happy holiday and a great new year.  Please keep this
great project alive.

clarf.
