Bug 521332

User-Agent:       Mozilla/5.0 (compatible; Konqueror/4.2; Linux) KHTML/4.2.95 (like Gecko) SUSE

In Yast2 (sw_single) I selected 170 packages from package group 'system' for update.
The update proceeded until 44% and then never finished the install of package aaa_base-11.2-30.2.i586.
Yast2 shows me a busy cursor (rotating balls) and the UI is not responsive (e.g. I cannot scroll the widget with package messages or close the app).

The last lines of /var/log/YaST2/y2log (at the end of this report) reveal that yast has forked an rpm process which does not finish and that it receives application close events (but does not react on).

Running ps shows me that the forked rpm is still alive after over 60 minutes (in whatever state):
root     26741  0.0  0.3   8364  4384 ?        S    14:55   0:00 rpm

On the other hand a check with rpm -qi shows me a history of three aaa_base packages which also lists the new one as being installed today at 14:55:55.

Could it be that the rpm process hangs in some post install?
I attached the rpm process with gdb and got the following backtrace:
