[PATCH] D25597: Try to fix buildbot failure in VirtualFileSystem caused by r284129.

I think the assertion is correct, there's something fishy with the inputs. The paths coming in should be absolute, and there should never be a .. at the start in a absolute path. This only fails on a single buildbot and doesn't reproduce anywhere else. @bruno any ideas?
