PATCH: make gaim backend indexer more robust

[Jamin Philip Gray <jamin pubcrawler org>]

I had some trouble getting the gaim backend to index my conversation logs.  It kept
getting array index out of bounds exceptions on certain files.  So I made a change
to make it more robust by skipping any file that causes an exception to be thrown.  

The patch is attached.
