Yes, that was stupid.  I'm really sorry about it.  I just committed a 
tentative fix, as you probably read on the cvs commit msg, handling "//" 
with BLI_convertstringcode, not using U.pythondir if equal to "/" and 
setting limits (max depth = 3, max dirs = 30 (dirs inside each dir also 
counted)).  Should be safe now.

Thanks for reporting,
