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 Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/963736 Title: thunderbird freezes at random : must be killed and reload Status in “firefox” package in Ubuntu: Confirmed Status in “thunderbird” package in Ubuntu: Confirmed Bug description: Thunderbird freezes at random. I must kill it then reload it. Sometimes the freeze happens when sending a mail. I had no problem in 11.10. It happens several times a day. The only pattern that I can currently see is that the freeze happens frequently when thunderbird is using the network. $ lsb_release -rd Description: Ubuntu precise (development branch) Release: 12.04 $ dpkg-query -s thunderbird Package: thunderbird Status: install ok installed Priority: optional Section: mail Installed-Size: 45256 Maintainer: Ubuntu Mozilla Team <ubuntu-mozillat...@lists.ubuntu.com> Architecture: amd64 Version: 11.0+build1-0ubuntu1 [...] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/963736/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
