App is crashing if DAV::creationdate is a string (as the standard requires)

[bohwaz]

Just like the ownCloud app was, the OpenCloud app crashes if the server sends a formatted date string value for DAV::creationdate. It expects a LONG, but this is incorrect, the WebDAV standard says this should be a date string.

With which server (version) did you experience this?
