Bug ID: 438682
Summary: Setting App to Use Material Style Results in
Segmentation Fault
Product: frameworks-kirigami
Version: 5.83.0
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: notm...@gmail.com
Reporter: jav...@imaginary.tech
Target Milestone: Not decided
SUMMARY
Setting a Kirigami program to use the Material style from a
qtquickcontrols2.conf file results in a segmentation fault, likely related to a
cyclic dependency on Kirigami's Units.qml.
STEPS TO REPRODUCE
1. Use KDE Frameworks 5.83.0
2. Create a basic Kirigami app; the template from KAppTemplate does the job.
3. Create a file named "qtquickcontrols2.conf" under "./src ".
4. Add the following contents to qtquickcontrols2.conf:
[Controls]
Style=Material
5. Load the file on the app as a resource, like so:
<RCC>
<qresource prefix="/">
<file alias="main.qml">contents/ui/main.qml</file>
<file>qtquickcontrols2.conf</file>
</qresource>
</RCC>
OBSERVED RESULT
When the Control's style is set to Material, Kirigami app execution results in
a segmentation fault as follows:
Cyclic dependency detected between
"file:///usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/kirigami.2/Units.qml" and
"file:///usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/kirigami.2/Units.qml"
*** Program received signal SIGSEGV (Segmentation fault) ***
If you set the style to any other valid value, the program will run. If you
replicate using a non-Kirigami template as your base, the program will run with
any valid Style.
EXPECTED RESULT
One would expect Kirigami app to start with the Material theme, as they did in
5.82 and prior versions of KF5.
