Bug#1129309: systemsettings crash with mesa-libgallium 26.0.1-2 (and previous version)

Package: mesa-libgallium
Version: 26.0.1-2
Severity: normal

Dear Maintainer,
despite updating the package "mesa-libgallium" to version 26.0.1-2, the
application "systemsettings" still crashes when attempting to retrieve 
system
information by clicking the "System Information" button. Notably, 
invoking the
same functionality directly via the command `kcmshell6 kcm_about-distro`
operates without issues, suggesting the problem is specific to the 
integration
within **systemsettings**.
I am unable to definitively determine whether the root cause lies within
"systemsettings" itself or a compatibility issue with the updated "mesa-
libgallium" library.
For reference, this issue was previously reported here:
https://lists.debian.org/debian-qt-kde/2026/02/msg00490.html

Thanks,
Antonio
