[karmic] apt_check.py crashed with SIGSEGV in pkgCache::FindPkg()

[Emilio]

Binary package hint: update-notifier

This happened twice in my systems, in both cases I was running synaptic, and it was installing packages. A red icon appeared on the tray, with an error that said something I don't remember, and then said this might be caused by broken dependencies - but the first error wasn't related with dependencies in any way.

Thank you for your report!

However, processing it in order to get sufficient information for the
developers failed (it does not generate an useful symbolic stack trace). This
might be caused by some outdated packages which were installed on your system
at the time of the report:

lsb-release: installed version 4.0-0ubuntu4, latest version: 4.0-0ubuntu5
python2.6: installed version 2.6.3-0ubuntu2, latest version: 2.6.4~rc1-0ubuntu1
python2.6-minimal: installed version 2.6.3-0ubuntu2, latest version: 2.6.4~rc1-0ubuntu1
update-notifier-common: installed version 0.88, latest version: 0.89

Please upgrade your system to the latest package versions. If you still
encounter the crash, please file a new report.

Thank you for your understanding, and sorry for the inconvenience!

The same error here, but the system didn't say anything about dependencies. It was about apt_check.py. I was searching new security updates and tried to confirm them when it happened.

Also affecting Lucid periodically. My system crashed while running this morning's update. On reboot, this message appeared and even apt-get update/upgrade in a terminal behaved oddly. I ended up updating via Synaptics Package Manager.

It may be related to bug 261523 - update-apt-xapian-index crashed with SystemError in open().
