Reply to myself (and maybe a ticket opening, let me know). I work on a fresh build of grass7_trunk, here is the problem:
There might be something wrong with the digitizer, especially with the ability to remove vertices. If you accidentally (I mean it's a nonsense) attemp to remove a vertex to a two-vertices line, then digitizer and gui immediately crash. After rebuilding the map, running v.report allows you to identify a zero-length segment. Notice this wrong line cannot be removed by v.clean and its dedicated rmline option (anyone know why?). Running v.edit with tool=delete you can remove the zero-length line, then everything runs fine again for your map. Hope this can help people puzzled by this rather frequent issue (at least for me ;-)). Vincent.
