I'm affected by this. Fresh installation of Kubuntu 13.04 64 bit. Thunderbird and FIrefox randomly hang, often after an idle period. Have tried changing theme to see if the oxygen-gtk theme may be the issue as suggested. This would seem to have solved the issue.
May be unrelated, but if thunderbird or firefox is launched from the command line they throw a critical glibc error: (process:3400): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed New to this - what can I do to help? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/963736 Title: thunderbird freezes at random : must be killed and reload To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/963736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
