Traceback report: list index out of range

I encountered a traceback with the dnf tracer plugin, here's the error message

Wir bitten, die Unannehmlichkeiten zu entschuldigen

(\n -> line break replaced)

Unfortunately, I cannot track down the cause of this.

Hello @xasx, thank you for the feedback

This is interesting for me

return self.instances and self.instances[0].is_interpreted

Why would it even check self.instances[0] when bool(self.instances) is False. I am gonna look at it.

I think this was caused by our dynamic use of psutil, since 08fed6a fixed that I'm going to close this issue, please re-open this if you hit this issue again.
