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 ?? ()

Without prelink:
    0x7ffff7e3f978 <_ZTVN12KQuickAddons21QuickViewSharedEngineE+56>:        
0x0000555555571af0
    (gdb) stepi
    0x0000555555571af0 in QQuickWindow::event(QEvent*)@plt ()


Kind regards,
Bernhard
