I want to create a new virtual machine, the wizard starts but after a few clicks it hangs. I can only cancel the wizard.
When I try again to create a new virtual machine, the 'New VM' wizard is only black.
Than I only can close virt-manager.

When I start virt-manager with --debug --no-fork I see nothing suspicious

Any idea why a default virt-manager on debian hangs
