Comment(by lutra):

 > I've imported freguesias.shp several times by v.in.ogr in the same qgis-
 grass-session and several times in different qgis-grass-sessions. the
 import worked all the time without any qgis-crash. the only thing is that
 I thought the first time that the import has already finished (just too
 impatient ;-)), but it wasn't.


 really weird. I have also updated qgis-trunk to 1.7.0-100 and now it seems
 that this problem become really rare. I can also import now the attached
 vector over and over almost without any problem. I got a crash but it was
 one among tens of attempts...

 issues?)


 as above, now it works almost without problems. Crashes doing this
 operation become rare. More common when adding more then one vector at the
 same time

 see above.

 and with vectors that are "big" (I'll attach a 13mb shapefile, in epsg
 3003, that can be used to replicate easily the crashes).

 after the first tests it become clear that there is (was?) no pattern.

 yes, VERY slow to scroll the attributes table. I don't see "short time
 freezes", if the table has just hundreds of records it freezes for many
 seconds.
