BTW: I suggest that the right mouse button always de-selects the active tool. Currently, when "New point" or "New controid" tool is used, right-click acts same as the left-click (digitises a new feature). Also, when the GRASS Edit starts, no tool should be active - currently "New point" is always active at a start.

I can't reproduce it with 0.8.1 (latest svn Release_0_8_0 branch). Right button does nothing. No crash, no error message.

Replying to [comment:5 lubaby]:
I can't reproduce it with 0.8.1 (latest svn Release_0_8_0 branch). Right button does nothing.
No crash, no error message.
I confirm. The crash is gone. I'll close the ticket. If the problem returns I'll re-open it. Thanks for the heads-up!
However the defect that right click digitizes point or centroid is still valid. I'll submit it in a separate ticket.

The bug is back. No segfault, but QGIS 0.8.2 svn 7045 crashes when I do the following:
1. add the any GRASS vector (eg. "archsites" from spearfish60 dataset r1)
2. open it in GRASS Edit
3. select one of the tools:
Move vertex
Add vertex
Delete vertex
Move element
Split line
Delete element
3. press right mouse button on the canvas - crash, no segfault:
