crash at: wcslen.c:30

[wabbit]

µTorrent was running with about 5-10 torrents when it suddenly crashed. It crashed when I was not at the computer so there was no user intervention.

I'm using Debian Squeeze 64bit with µTorrent Linux Debian 64bit v25376 with WebUI v0.385.

(Since the µTorrent Linux versions are unstable, it would be better to compile them without optimization flags so the backtraces will provide more information.)

I think I saw a fix for what looks like this get committed recently. Next would be for me to prepare another release. I am pretty swamped right now - I have not had time for a couple of weeks even to respond to forum posts.
