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

[Vlad Orlov (monsta)]

This is now fixed upstream. Attaching the patch for 1.18.x.

[Vlad Orlov (monsta)]

As the crash is random, and I couldn't reproduce it at all, I can't make an SRU for current stable releases of Ubuntu. But if anyone is still able to reproduce it, I can upload a patched package to my PPA for you to test.

[Ubuntu Foundations Team Bug Bot (crichton)]

The attachment "Fix crashes in the process of cancelling the bg change operation" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.
