Comment 2 Martin Stransky 2013-02-26 08:43:02 UTC 
Gustavo, you can easily generate a debug package from the Fedora srpm - there's debug_build option for that in our xulrunner package. Turn it on and try to catch the backtrace again. It also may help to launch xulrunner with Efence/valgrind.
Comment 3 Gustavo Luiz Duarte 2013-02-26 14:46:20 UTC 
Unfortunately xulrunner fails to build on ppc64 when debug_build is enabled. Follows the error message:

Comment 4 Gustavo Luiz Duarte 2013-03-19 13:34:52 UTC 
Please, add the following patch to xulrunner on Fedora [17,18,19,20]. It fixes the Firefox crashes on ppc64.
