I am on Mac, I can't get crash dump. In the link, it said only tested in
linux.
Is there any instruction about how to make it work in Mac?

Would it be possible to provide us a part of your project that does the SVG canvas drawing so that we can try and reproduce the problem here.

Added Dartium-Crasher label.

I will try if I can reproduce the crash in a simpler project.

Once we get a repro we'll bump back to High Pri.

Removed this from the 1.6 milestone.
Removed Priority-High label.
Added Priority-Medium label.

I uploaded my project trough gmail on July 13, but it didn't show up here. I'm attaching it here again.

A simplified project is attached. To reproduce the crash:

1. Set Preferences->Ran and Debug->Break on exception to None. (This is new bug that break on uncaught exception doesn't work).
2. left click on the canvas and drag while holding the left mouse, a blue rectangle will show up.
3. cover the two '0' with the blue rectangle then release left mouse button to select the two blocks.
4. Once the two block selected, their border will change to orange.
5. click ctrl+g key

Dartium crashed. The crash does not happen every time. If it didn't crash, just stop the project and repeat step 2~5.
