Gallery 2.0.2 Security Fix

Somebody from the Gallery development team pointed out a security problem on Photos:

I’m writing to deeply, humbly and profusely apologize because I inadvertenly brought down your G2 just now.

One module from G2 is broken so one can construct URLs that may remove any file on the host that is writable by the server process. So please do upgrade to Gallery 2.0.2 if you are using Gallery 2 and don’t want your files to vanish some day!
