Same as for Bug #15212. Please provide a backtrace with debug symbols,
and/or some more details on the use case .. what exactly you were doing
in Thunar while it crashed ? Which view is used ? Which side-pane ?

It seems like thumbnailer gets free'd before 
thunar_thumbnailer_queue_async_reply is run.
However I don't think that's a valid reproducer and we can't just return if 
thumbnailer is NULL.
It would be much better if you (or OP) could find a reliable way to reproduce 
the crash.
