>Description:

Trying to debug firefox (that is: build with options debug-info, and
use
	cd /usr/pkgobj/www/firefox/work/build/dist/bin
	./run-mozilla.sh -g ./firefox

to start it), gets me immediately into:

(gdb) run
Starting program: /usr/pkgobj/www/firefox/work/build/dist/bin/firefox 
[New process 21084]
[New LWP 15 of process 21084]

(firefox:21084): GVFS-RemoteVolumeMonitor-WARNING **: remote volume monitor with dbus name org.gtk.Private.HalVolumeMonitor is not supported
[New LWP 111 of process 21084]
/usr/src/external/gpl3/gdb/lib/libgdb/../../dist/gdb/infrun.c:7146: internal-error: [LWP 15 of process 21084] has inconsistent state: trap_expected=1

A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
