I don't think this is a bug. It's pretty common on linux for any large (i.e. more than a few milliseconds) change in the system clock to break your system - the OS generally prefers to blow up instead of reading or writing files that appear to be written in the future.
Somebody else tested this on Windows and the bug doesn't exist there. So I'm assuming this is a bug in Wine because there shouldn't be any problems with Guild Wars 2 if the time changes.
