Several reports of crashes like this, all with GTK 2.4. Could someone for
whom it happens reliably try the suggestion in the error message? Eg:

$ rox --debug
(gdb) run -n --sync
(press Ctrl-C once ROX-Filer has started)
(gdb) break gdk_x_error

(if that doesn't work, try this:
	(gdb) p XSetErrorHandler(abort)
)

Resume (continue) the filer with:

(gdb) c

Then do something to make it crash. When you get back to the (gdb) prompt=
,
ask for a backtrace (and send it to us!):

(gdb) bt

If you get "Program received signal SIG35, Real-time event 35.", this is
due to a directory changing rather than a bug. Use 'c' to continue
again...

These instructions are somewhat untested, as it won't crash reliably for
me... let us know if you have problems.
