3. press right mouse button on the canvas - segfault:

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.
