The patch looks correct.

But if you can't get the automatic printing to work, the patch should still let
you get the information you need. Just replicate the deadlock with the patch
applied with the program running under gdb, interrupt the program, then at the
gdb prompt type:

    print CAIRO_MUTEX_LOCK_FILE
    print CAIRO_MUTEX_LOCK_LINE

and give me the results of that, (correlated with a stack trace showing the
deadlock---which could be just a pointer to a stack trace already posted).
