Description Igor Kushnir 2022-01-09 15:27:40 UTC 
Application: kdevelop (5.7.220370 (22.03.70))
 (Compiled from sources)
Qt Version: 5.15.2
Frameworks Version: 5.88.0
Operating System: Linux 5.15.7-1-MANJARO x86_64
Windowing System: X11
Distribution: Manjaro Linux
DrKonqi: 5.23.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
1. Install kdev-python and enable the "Python Support" plugin, but not "Python Debugger (PDB) support" plugin, in a session that contains 3 projects (kate, ktexteditor, syntax-highlighting).
2. Open a Python file (kate:addons/latexunicodecompletion/fetch_unicode_table.py). This file has been an active document for many session restarts (because I was testing Source Formatter settings and never changed the active document).
3. After many sesison restarts, unload the "Python Support" plugin and restart this KDevelop session again.
4. Start the KDevelop session. Check out Source Formatter tab in KDevelop settings. Let the session run for a while. Quit the session => an assertion fails.

The crashed session's output contained many identical lines:
kdevplatform.language: Cannot load a top-context from file "/home/igor/.cache/kdevduchain/kdevelop-{42384534-ccf8-442d-b6a9-9406038ea72f}/topcontexts/1" - the required language-support for handling ID 100 is probably not loaded

And the final two lines of the output:
kdevplatform.language: Factory for this type not loaded: 64
ASSERT: "false" in file /home/Fast_storage/kdevelop/kdevplatform/language/duchain/types/typeregister.cpp, line 53

The reporter is unsure if this crash is reproducible.
