Comment (by harrikoo):

 Hi!

 I still haven't managed to catch the bug on video; however, I've been
 running a self-compiled version (r67579) of the grass70_release branch for
 several weeks now, and can report some improvement.

 The bug itself has not gone away, I still occasionally get crashes, always
 connected with breaking boundaries – I discovered this after turning the
 automatic breaking of boundaries off. So now the crash never happens while
 drawing, only when using the "Break selected lines/boundaries at
 intersection" -tool. Opening the map after a crash shows, that new
 vertices have indeed been created at the intersections of the boundaries,
 but the boundaries have not been connected into areas.

 However, with this version, the vector can be opened again with the
 digitizer, and after reclosing the vector, it seems ok. A simple rebuild
 will not remove the extra coor data, but opening and closing it in the
 digitizer does.

 Since now the vector resulting from the crash can be reopened in the
 digitizer without losing any work, the severity of the bug could perhaps
 be decreased.

 I will update my version again at some point, but it is difficult to stay
 current, as the bug does not manifest regularly, and I still can find no
 systematic way to reproduce it.
