Description

https://openqa.suse.de/tests/4853225 shows an interesting error after the VNC connection failed. I think the VNC connection issue is not the root cause of this issue and is handled in different tickets (e.g. https://progress.opensuse.org/issues/71236). However, it seems like os-autoinst crashes on tearing down the connection. Here's the interesting part of autoinst.log. So first you see the connection errors:

Looking at the "Use of uninitialized value" we might also face an upstream bug but I'm unsure if stuff like $_[1] indicates some wrongly passed parameters so a quick look from a skilled perl programmer who's into openQA's codebase would be highly appreciated :)

I think this is something we had in forever (hence setting "Low") and is mostly a case of "misleading error output" so I regard it as "Feature requests" category rather than a regression. Also not including in our backlog. We have plans for tickets in related areas which might improve the behaviour indirectly anyway.

Update: after reinstalling perl and installing it again (besides all openqa packages) it works:

zypper rm perl
zypper in perl
zypper in openvswitch openQA openQA-worker os-autoinst os-autoinst-openvswitch

I just made sure the repo I am installing it from is:
http://download.opensuse.org/repositories/devel:/openQA/openSUSE_Leap_15.3/

And 

rpm -q perl-Mojo-IOLoop-ReadWriteProcess
perl-Mojo-IOLoop-ReadWriteProcess-0.32-lp153.33.1.noarch

is the same version before and after, so I am not sure what was causing that exception...
