Bug#827306: general: won't open file browser/manager if several other programs are already open

I hope that this is what you needed:
sudo gdb nautilus
(gdb) r

Ok, it seems your debugger is not installed.  Please follow the
instructions given in another nautilus reported bug:

"Looks like a livelock. Please install nautilus-dbg and gvfs-dbg, and
obtain a gdb backtrace of the locked process.

See http://wiki.debian.org/HowToGetABacktrace for more information."

In addition, please reply to the bug report address and not directly to
me (I am subscribed to this bug) since otherwise the maintainers of the
package will not see any of your replies since they are held out of the
bug tracking system.

Regards,
