I'm one of the maintainers of the Tango Icon Theme for Thunderbird and I am able to consistently reproduce this crash as well (turning on notifications and using our theme).
As the theme consists entirely of CSS and PNG images, it's hard to imaging how we'd be causing a crash, but it seems we are. I'm thinking this should be pushed upsteam to Mozilla as our theme is probably exposing a bug in Thunderbird. -- Latest version hungs after downloading new mail https://bugs.launchpad.net/bugs/119836 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
