Bug ID: 467434
Summary: NeoChat crashes and accounts are deleted from config
when server is unreachable on startup
Classification: Applications
Product: NeoChat
Version: unspecified
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: General
Assignee: fe...@posteo.de

Target Milestone: ---
Application: neochat (23.03.70)
(Compiled from sources)
Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.15-200.fc37.x86_64 x86_64

Distribution: Fedora Linux 37 (Thirty Seven)
DrKonqi: 5.27.2 [KCrashBackend]
-- Information about the crash:
I have two accounts configured in NeoChat: My public matrix.org account, and an
account on a company internal home server that is only reachable through VPN.
When I first encountered a probably related problem yesterday, KDE session
restore started NeoChat before I had connected to the VPN, and today I
reproduced this scenario intentionally manually (a few times to be sure). The
result is that the server name doesn't resolve, and apparently NeoChat doesn't
handle this error condition well at all.
After displaying "Loading..." for a while, it doesn't only crash, but
afterwards both accounts are deleted from ~/.config/KDE/neochat.conf!
Note that at this point, it had already successfully connected to the
matrix.org account. However, the unreachable server is stored as
ActiveConnection in ~/.config/neochatrc. These are the last few log messages:

KCrash: Application 'neochat' crashing...
The behaviour looks different when the reachable server is the
ActiveConnection. Then I already get to the normal view for the matrix.org
account and can read rooms etc. while it's still trying to connect to the
unreachable server. Once it finally fails, the room list goes away and the
"Join some rooms to get started" message is displayed instead. Scrolling a bit
in the still active room crashes in LinkPreviewer::setUrl() because
Controller::instance().activeConnection() returns a nullptr now. I can submit a
separate bug report for this if necessary.
The crash can be reproduced every time.
