From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.6) Gecko/20011120 Description of problem: mozilla works fine for user A. For roor and user B, it segfaults on start. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.run mozilla as root or user B 2.mozilla segfaults 3. Actual Results: [root@yakuza root]# mozilla Segmentation fault Expected Results: mozilla should have worked Additional info: [root@yakuza root]# rpm -qa | grep mozilla mozilla-js-debugger-0.9.6-0 nautilus-mozilla-1.0.6-1 kdebindings-kmozilla-2.2-2 mozilla-mail-0.9.6-0 mozilla-psm-0.9.6-0 mozilla-0.9.6-0
I couldn't do mozilla -g -d gdb (It wouldn't even get into gdb because of the segfault.) So I tried running mozilla-bin directly inside gdb, without the wrapper script. Now I can get a backtrace. Hope this is useful. [root@yakuza root]# gdb /usr/lib/mozilla/mozilla-bin GNU gdb Red Hat Linux (5.1-1) Copyright 2001 Free Software Foundation, Inc.
