Dear Maintainer, tried to reproduce this issue and attached backtrace is created by - using a minimal buster amd64 qemu VM - installing a minimal plasma desktop - logging into graphical session - via ssh: running "prelink -mR /usr/bin/plasmashell" - via ssh: running "DISPLAY=:0 /usr/bin/plasmashell --replace"
The crash seems to happen on an attempt to resolve the member QQuickWindow::event through the executables .plt section. For some reason with prelink this pointer looks damaged and points not into the .plt section: With prelink: 0x7ffff7e3f978 <_ZTVN12KQuickAddons21QuickViewSharedEngineE+56>: 0x0000551d8b171af0 (gdb) stepi 0x0000551d8b171af0 in ??
