Navigating movielist repeatable crash

[alphacabbage1]

It's looking more file than directory specific now. So far, I've only found two directories that show the problem:

/media/hdd/TV/Film
/media/hdd/TV/Film/_World/European/FR

The latter isn't particularly heavily populated so it's not looking like a size thing. In both cases the crash happens at a repeatable point in the list -- whether approaching from above (via down-arrow) or below (up-arrow). When there's more time, I'll try copying the smaller directory to a temp location and knocking out files/recordings one-by-one until the crash doesn't happen.

Meanwhile, OpenWebif sits and spins indefinitely when trying to parse /media/hdd/TV/Film and the debug logs shows:

I'll keep plugging away but it may be a while.
