I can provide the two specs that cause the error via mail. Unfortunately, i cannot share them publicly here.

You don't seem to have sponsoring turned on or a coffe link, but i would gladly tip you one or another beer since we really enjoy your work!

hi @pkunze,

If it's possible, you can share them with me via email as well (arnold_galovics(at)docktape(dot).com) and I can strip it down to a point where it could be used for the automated tests in the project.

On the coffee, thanks for the nice words, I'll look it into. :-)

I somehow missed your comment. Sorry for my late response. I will send them to you on monday. :)

I just sent them as discussed above. :) Sorry for the delay!
