readSymbolicLink is broken, it assumes that readlink(2) null terminates its result when it doesn't. this causes all sorts of badness.

This should fix it, although all my CVS trees are hosed right now (now how did I manage to break something in the backup tree?) and I can't actually test it: <patch snipped>

Thanks, I'll check it in. As you probably guessed, this stuff hasn't had any testing yet. Cheers, Simon
