Follow-up Comment #4:

Closing this as duplicate

see bug #2595 (loopif results in NULL reference for incoming TCP packets)
which shows a different result of roughly the same bug.

This bug came from using sys_timeout() in loopif_output() (which generally is
a bad solution).
So, this is also a bit dependent on solving bug #1902: 'Timeouts and
semaphores/mailboxes are too tightly integrated', but bug #2595 solves this
better, so that loopif does not depend on timeouts.
