I don't know how GetFileAttributesEx() could crash (/me confused).
The only thing I can think of would be if the paths were longer than
MAX_PATH (254 chars). But in the program files folder, I don't think
there are such long paths.

If that's not the case, then there must be something wrong way before
that (and most likely in a completely different part of the cache code)
which would corrupt the TSVNPath object which we pass to
GetFileAttributesEx().
