Reproducible¶

Fails since (I guess) https://github.com/os-autoinst/os-autoinst/pull/764 was introduced

Expected result¶

Last good: 0345

Problem¶

Error message is clearly suboptimal when perl wants to call a method on an error string which came back from VNC -> Improve that but also fix the underlying problem

Further details¶

Always latest result in this scenario: latest
