Bug 391608

Application: systemsettings5 (5.12.3)

Qt Version: 5.9.4
Frameworks Version: 5.44.0
Operating System: Linux 4.15.7-300.fc27.x86_64 x86_64
Distribution: "Fedora release 27 (Twenty Seven)"

-- Information about the crash:
- What I was doing when the application crashed:

I tried to create a Bonjour account (local XMPP, using Telepathy Salut), which failed with:
"This IM Account cannot be created - a Telepathy Connection Manager named 'salut' is missing or it cannot handle protocol 'local-xmpp'. Please try installing salut with your package manager."

When I closed System Settings afterwards, it crashed.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
