I tried to obtain updates with Yast on SuSE 10.3 using the online
update and get this:
YaST got signal 11 at YCP file OnlineUpdateCallbacks.ycp:524
/sbin/yast2: line 386: 4452 Segmentation fault $ybindir/y2base $module
"$@" "$selected_GUI" $y2_geometry $y2qt_args

Also tried to add software via Software Management and get the same
thing.

Any idea what is going on and how to fix this?

Thanks!
