Control: found -1 0.17.0-1
Dear Maintainer,
I tried to collect some more information and could
reproduce the issue.
I guess the interesting thread is not that with
the main function.
Instead it is that thread with the tox_kill / __GI_abort.
There I think that tox_kill in libtoxcore2 is reached
while not completely shut down, therefore aborts in
this LOGGER_ASSERT.
Unfortunately that message was not printed on stderr/out.
There exists upstream issue [1] based on this bug,
with a workaround mentioned.
This issue can already be seen in Buster/stable too.
Kind regards,
Bernhard
