We may not show the backtrace, but it's prohibitly expensive to generate, so don't. If someone wants a backtrace they can use the appropriate G_DEBUG environment variable plus GDB. https://bugzilla.gnome.org/show_bug.cgi?id=676855

|
|
* close themselves and don't do so within a reasonable amount of time, and
|
|
* therefore we always use the same callbacks. It's possible that we might
