Comment 12 for bug 135228

Hmm, ok. I did not know how to provide debugging information for this bug because the crash happens when I log in. I have used GDB in the past to provide backtraces, but AFAIK there is no way to start GDB or something like that to get a backtrace before I log in, or is there? I've read the information on the wiki for debugging procedures - https://wiki.ubuntu.com/DebuggingProcedures - the document which describes my situation most closely there is probably - https://help.ubuntu.com/community/DebuggingSystemCrash - but that only deals with reproducing crashes on a text console, which is probably not what I need to do if my crash happens when I log in to GNOME.

To be honestly I don't know how to provide the correct debugging information then, there is no info on the Ubuntu wiki either. The only way I could think of was providing some log files, I thought the .xsession-errors file was useful?
