Bug ID: 381284
Summary: Double-delete KateScriptActionMenu::cleanup()
Product: frameworks-ktexteditor
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: kf...@kde.org
Target Milestone: ---
KDevelop master, Qt 5.8, KF5 master.
This doesn't seem to be a problem with my other combo: KDevelop 5.1, Qt 5.7,
KF5 5.34. So something must have changed/regressed.
Howto reproduce:
valgrind --track-origins=yes ./plugins/quickopen/tests/test_quickopen
testProjectFileFilter
Valgrind trace:
