[Sense Egbert Hofstede]

This crash has nothing to do with the default Lucid packages, but is bug #518548, and caused by Ground Control.

It crashed when Ground Control was finalising the downloading of a branch that had been requested with "Fix Bug".

Moving back to private since my CoreDump.gz is still attached. Whoops.

I'm afraid we'll have to wait for the retracer to go over this since the Python part of the crash isn't very useful at the moment. However, I'm afraid it won't become much more useful since Ground Control has no debugging symbols and is not available in the default install, which means the retraces can't understand it.

Sense,

I looked through the core dump, and didn't see anything sensitive.

I've experienced similar Nautilus segfaults with Ground Control installed after upgrading to latest Bazaar (from https://launchpad.net/~bzr/+archive/ppa).
