If you want to get a clean repository again, you could also use a "git 
clean -dxf". But be very careful with that command. It doesn't ask 
before deleting anything that is not versioned.

If you get the error again, it would be interesting to find out what 
caused it. That sounds like something that shouldn't happen. It seems 
that the wscript uses a simple file modification time to find out 
whether the cache has to be re-generated. So if your system time changed 
backward, that might could lead to such errors.
