mythvideo segfault (Possibly leaving a dir before screenshot is downloaded?)

[Damian O'Sullivan <damian@…>]

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.

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?

(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.
