Thanks for your guiding. I should have read the 
more carefully :).

Apparently GRASS dbf driver is guilty, not QGIS. Step by step:

1. Built GRASS, cvs 19.08.05 10:00 AM, with:

CXXFLAGS="-g -pipe"
CFLAGS="-g -pipe"

2. ulimit -c 300000
3. qgis
4. digitize a line in QGIS GRASS digitizer, fill in only the numerical
column (wys) and leave the char column (nazwa) empty
5. crash:


QgsGrassEdit::displayDynamic Points = 0 type = 0
No DB record
updated line = 1210
node = 1417 mNodeSymb = 12
node = 1418 mNodeSymb = 12
QObject::connect: No such signal QTabWidget::void currentChanged(QWidget*)
QObject::connect:  (sender name:   'tabCats')
QObject::connect:  (receiver name: 'QgsGrassAttributesBase')
Value: 1196
Value: dbmi: Protocol error
Broken pipe

6. gdb /usr/local/grass-6.1.cvs/driver/db/dbf core.32751

Daniel, I'm sending over the core for you in priv like you asked.
