Application: kate (21.08.1)

Qt Version: 5.15.3
Frameworks Version: 5.86.0
Operating System: Linux 5.11.0-36-generic x86_64
Windowing System: X11
Drkonqi Version: 5.22.5
Distribution: KDE neon User Edition 5.22

-- Information about the crash:
- What I was doing when the application crashed:
1. Kate was open with several files from an sftp source when i shutdown my machine.
2. Start my machine the next morning
3. Kate is restarted and tries to restore the previously open files
4. When the system starts up the network might not be ready (yet) and this leads to load errors for the SFTP files
5. Kate crashes
6. After the crash i can simply press restart application and the previous session is restored correctly (with SFTP files). Most likely by the time i press restart the network is up and running.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
