Do you have a > backtrace for the network process crash? I already talked about that with Carlos. There was no network process crash involved (at nothing showed up in coredumpctl) 1409297 4 mcatanzaro 2018-03-26 08:50:47 -0700 Drat, then it's going to be quite hard to debug, because we don't have any close why the network process is quitting. 1411029 5 cgarcia 2018-04-02 02:09:50 -0700 I don't know what xreader is, I've tried with evince browser plugin and I can't reproduce the crash. 1411072 6 mcatanzaro 2018-04-02 07:41:19 -0700 Looks like xreader does not exist in Debian. 1411272 7 mcatanzaro 2018-04-02 15:23:25 -0700 (In reply to Michael Catanzaro from comment #6) > Looks like xreader does not exist in Debian.
