Hello list,
A panic log sent to me by a user looks like this:
Somewhat helpless...

one of my apps seems to be causing Kernel Panics at the moment the
remote client connects to the Mac.

It uses a custom service, the code is partially altered code from the
RFCommServerSample; the code for incoming connections looks like this:
-(void) newRFCOMMChannelOpened:(IOBluetoothUserNotification *)
inNotification channel:(IOBluetoothRFCOMMChannel *)newChannel {

    if ((newChannel)&&[newChannel isIncoming]&&([newChannel
getChannelID]==serverChannelID)) {

		if ([newChannel setDelegate:self]==kIOReturnSuccess) {

			RFCOMMChannel = newChannel;

			[RFCOMMChannel retain];

			[self stopProvidingServices];

			[connectionTarget performSelector:handleRemoteConnectionSelector];

		} else {

			RFCOMMChannel = NULL;

		}

    }

}

Does anybody have an idea what's going wrong here?

Besides the fact that an application running with normal user
privileges shouldn't ever be able to cause a Kernel Panic.
