Hi Christian,

i still see some occasional errors running r36094
Jul 16 19:32:46-511103 core-4127 ERROR Assertion failed at transport_api.c:754.

plus a lot of (probably caused by flaky connectivity...)

second
Jul 16 19:52:57-972485 cadet-p2p-4116 ERROR  core wait time 2069738 µs > 1

after some more time
Jul 16 20:07:41-570240 nat-4126 WARNING Asked to validate one of my addresses 
and validation failed!
