Huhu .. dumps core when using Virtual Machine Manager !

[specs32]

I have this problem for quite a while now (years). Don't know what to do...
I run a freshly updated Endeavour OS (Arch)
If you like more Infos I am happy to investigate.

When I close the Virtual Machine Manager after starting my VM the core dump occurs. This error is reproducible (happens every time). The docklike plugin reloads instantly and normal operation can be continued.
