Filemanager freezes Photivo.

[GoogleCodeExporter]

Great work with filemanager! It's a new thing, so there are some problems ... 
(Ubuntu 11.10, .orf and .nef)

When I choose new directory - sometimes Photivo freezes. No segfaults, gdb 
doesn't show any critical errors - just no response. I thought, that's the 
matter of files - it hangs much often when there's more than ~200 files in 
directory. But there's no rule.

Gdb says:

Looks like the problem with X and the threaded thumbnail loading. I had hoped 
we caught that one. :(

Can you say if the hanging only occurs when you choose a new directory while 
the thumbnails in the old one are still loading? I hope that’s the case, 
would make the bug a lot easier to hunt down.

Well, it's strange.

I've made test - fast and slow run through the directories.

In the fast run I didn't wait for thumbnail for the last file. In scenario 
'click, go back, click another directory, go back', filemanager's survived much 
longer - well, it's hard to say, if it wasn't my fault (too slow click 'back').

In the slow run I've been waiting to the last thumbnails. Then I was able to go 
back, but choosing another directory it was lottery.

It seems QThread::isRunning() sometimes returns true when it shouldn’t, 
causing an infinite loop. I’m not sure why this happens but pushed a quick 
hack that forces the loop to exit after 500ms. This should take care of the 
hanging and I hope it doesn’t break anything else. Please test!

Well, 5 minutes of navigating between directories, and no freezes so far :)

I found a way to reliable reproduce the hang. I’m still not sure of the cause 
(Windows is completely fine btw) but may have found a workaround. Haven’t 
tested Ubuntu but with Fedora it seems to work fine.

No hangs up since latest patches. Good work!
