    Description

      This was originally reported here: https://bugzilla.suse.com/show_bug.cgi?id=1243717

      I use openSUSE 15.6 as my daily driver with latest KDE/Qt/VirtualBox from the OBS:

      I run a VM with Windows11 non-stop throughout the entire working day. On May 22nd I had upgraded to Plasma 6.4.x beta + Qt 6.9.0 from OBS. Since the upgrade, VirtualBoxQt and VirtualBoxVM executables crash 2-3 times with very similar stack traces.

Another stack trace from VirtualBoxQt. I had started it and immediately attached gdb so I can poke around in the internals when it crashes. Please let me know if there is anything else I check.
