Comment 1 Luigi Toscano 2016-08-03 10:53:38 UTC

There is another bug which is triggered by selecting a channel and marking "Join on Connect". The backtrace is different, but I suspect that the root cause is the same (still about the updates of the list of the servers); maybe not, in that case I will file another bug.

Comment 2 Eike Hein 2016-08-03 15:04:18 UTC

I can't reproduce either of these crashes.

Comment 3 Luigi Toscano 2016-08-03 15:37:01 UTC

Consistently reproduced on a fresh profile, but I was not precise: it is:
Go to "File" menu, "Server List", select a server and expand it (for example, expand "Freenode"), then select one of the servers ("chat.freenode.net:8001", not sure it's the upstream default or Fedora's one), and then  press "Edit".

Comment 4 Eike Hein 2016-08-03 15:40:27 UTC

Tried both, no crash ...

Comment 5 Eike Hein 2016-08-03 18:45:32 UTC

*** Bug 366370 has been marked as a duplicate of this bug. ***

Comment 6 Eike Hein 2016-08-03 18:48:26 UTC

Git commit 4fa92f7e55dea6354a7dbeae1ddf62c4357912e2 by Eike Hein.
Committed on 03/08/2016 at 18:46.
Pushed by hein into branch '1.6'.

Fix copy constructor not setting m_bypassProxy.

This caused crashes all over the place because now operator== fails.

This will need a 1.6.2 hotfix release.
