I observe a crash sometimes at the end of an upload. After investigation, it seems to be caused by a missing setter in WTClient.m, where the authentication is not retained when it should be. Here is a proposed setter:

• (void)setAuthentication:(CFHTTPAuthenticationRef)auth { if(auth != authentication) { if(authentication) CFRelease(authentication); authentication = auth; if(authentication) CFRetain(authentication); } }
