openSUSE 11.0 with KDE4.2 Factory repositories, next to others ;-)

Happened between yesterday and today. Can't do any updates anymore, because of error

YaST got signal 11 at YCP file /usr/share/YaST2/clients/online_update_select.ycp:83
/sbin/yast2: line 421: 12085 Speicherzugriffsfehler $ybindie/y2base $module "$@" "$SELECTED_GUI" $Y2_GEOMETRY $Y2UI_ARGS

Ok, there are many questions and answers about this subject, dating back to 2007.

I tried to get along and failed. This is what did NOT help :-(

-delete the zypp db -> There are no files like that
# rm /var/cache/zypp/zypp.db /var/cache/zypp/zypp.db-journal

-reorg the pkg mgt
# rpm --rebuilddb
# zypper ref
# zypper up

- update with console yast
-> no change

- deactivating all repos and activating them again with console yast
-> no change

- just a helpless try: Throw away the repo infos by renaming /var/cache/zypp to a tmp name
-> no change, though all repos get reread from update

From those other ideas i take the fact, that i MUST get rid of this zypp.db, but where is it? Has it a different name?
