Well this is the info Ubuntu collects from its crash logs and the back
traces it generates. 

I don't know what to suggest - this is the information they are giving
us. Their debugging procedures and bug triaging procedures use gdb,
their automatic crash dump process (apport) does the same I think.

It's not *my* bug so I can't get any more info..
