Re: [Rhythmbox-devel] strange compile issue

[James Cotton <peabody124 gmail com>]

Thanks, that allowed me to catch it.  I attached the
backtrace.  Looks like the error may not have come out of
rhythmbox.  I am going to try recompiling all of the libraries
referenced in that dump and I'll post back.

You need to add "handle SIG33 pass nostop noprint" to your ~/.gdbinit.
That will stop the real-time events from stopping gdb.
