Description

I apologize in advance for this horrible issue report. I noticed this a few weeks ago, forgot to report it and since then removed my configuration. At the moment I have no time to create an example.

I just thought I would let you guys know I ran in to this. If you can easily reproduce it: good. If not you can close this issue.
