Sorry I can't provide better summary. I think the following is what caused
it. The following is in Gallery view.

I started a meta download for a TV episode. The coverart appeared after a
few seconds so I assumed there was no screenshot. I backed up a couple of
directorys. Left the room and came back and myth had segfaulted. The logs
show that the screenshot had downloaded before it crashed so I think it
may be that I had left the directory it was trying to display the
screenshot it. My theme shows screenshot for a video if it exists.

BT attached.

Comment(by Damian O'Sullivan <damian@…>):

Just to test my theory I tried a few more times. If I did not change
directory until screenshot had downloaded there was no problem. If I did
myth would segfault. I guess the buttontree is becoming invalid as soon as
I change directory?

Comment:

(In [22815]) Fixes #7510. Reverts r22723. I have a better way of
handling what I was initially trying to do that will prevent segfaults and
be much cleaner.
