Bug ID: 448166
Summary: Assertion failure in TypeSystem::ensureFactoryLoaded()
after unloading Python Support and restarting
Product: kdevelop
Version: unspecified
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
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.
