As a test, I disabled the Ubuntu-Mozilla-Daily PPA, uninstalled all versions of Firefox, and then installed the "official" Firefox-3.5 package for Ubuntu. Attempting to launch Firefox-3.5 results in the same behavior as described above and running it from a terminal results in the same 'bus error' output.
Specifically, the version of Firefox-3.5 I'm using is : ' firefox-3.5: Installed: 3.5.2+nobinonly-0ubuntu0.9.04.1 Candidate: 3.5.2+nobinonly-0ubuntu0.9.04.1 Version table: *** 3.5.2+nobinonly-0ubuntu0.9.04.1 0 500 http://us.archive.ubuntu.com jaunty-updates/universe Packages 500 http://security.ubuntu.com jaunty-security/universe Packages 100 /var/lib/dpkg/status 3.5~b4~hg20090330r24021+nobinonly-0ubuntu1 0 500 http://us.archive.ubuntu.com jaunty/universe Packages ' Please refer to bug #419980 -- https://bugs.launchpad.net/ubuntu/+source/firefox-3.5/+bug/419980 -- for a full report. -- Firefox 3.5.4pre dies with "bus error" https://bugs.launchpad.net/bugs/419566 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
