Made a "strace gaim". I have seen that gaim was crashing just after opening the file .gaim/pref.xml So I removed that file and it solved the problem.
I have attached the buggy pref.xml ** Attachment added: "buggy pref.xml file" http://launchpadlibrarian.net/7934325/prefs.xml -- [apport] gaim crashed with SIGSEGV when launching Gaim https://bugs.launchpad.net/bugs/118390 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
