Status changed to 'Confirmed' because the bug affects multiple users.

Precise Beta 1: tried to install some packages; closely to 100%, progress window became unresponsive, and stayed so for >15 min; it crashed after attempt to close it.

Synaptics crashed after uninstalling old kernel packages.

Crash report is attached.

Generally, you should report a new bug and let the Apport system to process the crashdump,
instead of attaching a HUGE crashdump to the old bug reports.

I suggest you to report a new bug, post the new bug number here, and then remove this crashfile.

@Bob:

Thanks for the suggestion, but since Precise(?) Apport does not work as expected and does not report crash files!
So i had to do it by hand...

Oh, it looks like your Apport problem is already known as #994921, and you can make a vote for it;
try to apply the workaround, then reboot and try to report your Synaptic crash, this time it should work.

Manual attaching of unprocessed crash files is not a good approach though:
Launchpad's Apport retracing service doesn't seem to be able to process them directly.
