SIGSEGV in TaskGroupingProxyModel via
QConcatenateTablesProxyModel (use-after-free in task
proxy model)

thread apply all bt full
Platform Wayland
OS / distro Arch Linux, kernel 6.19.9-arch1-1 hardened
KDE Plasma version 6.6.3
KDE Frameworks version 6.24.0
Qt version 6.10.2
TaskGroupingProxyModel::data() accesses a stale proxy index with the telltale
0xfefefefefefefefe fill pattern, pointing to a use-after-free.
The bug happened when logging in. My external monitor stayed dark, the laptop
built-in display was on. I had to ctrl-alt-f3 and ctrl-alt-f2 and then
plasmashell crahsed and restarted and was usable. Generating this backtrace.
