-- Information about the crash:
I logged in to Plasma 6.7.0 on Wayland in a Fedora 44 KDE desktop installation.
A crash notification in Reminders/kalendarac was shown after about 10 s.
kalendarac crashed in QMetaType::isValid which had an invalid pointer this
based on the following gdb output.
(gdb) frame 5

/usr/src/debug/qt6-qtbase-6.11.1-1.fc44.x86_64/src/corelib/kernel/qmetatype.h:2695
2695 return d_ptr;
(gdb) p this
$1 = (const QMetaType * const) 0x55ca82f7f8f8
(gdb) p *this
❌ Cannot access memory at address 0x55ca82f7f8f8
(gdb) p d_ptr
❌ Cannot access memory at address 0x55ca82f7f8f8
I've seen kalendarac crash with different traces <10% of times I've started
Plasma as I reported at https://bugs.kde.org/show_bug.cgi?id=519668

The crash can be reproduced sometimes.
