Well, I for one never had such a problem as Jarek and Dylan describe -
QGIS never corrupted any GRASS vector for me. Even if QGIS crashes
during digitizing, v.build always helps, and QGIS doesn't crash that
easily these days; v.digit freezes or crashes for me more often AAMOF.

Honestly, QGIS 0.8 provides a really good vector digitizing tool for
GRASS. Using it is more convenient and time efficient than using
v.digit, and it doesn't suffer it's numerous problems (has it's own
problems though, yet less harmfull that those in v.digit; and they are
being fixed).

If you found bugs in QGIS GRASS digitizer please report them. There is
a major bug squashing ongoing in QGIS currently, your input could help!
