Hi Scott,
sorry that it took me so long to get back to you, I was swamped with other
things here.
As you said, the crash must have been caused by something completely
different as I cannot reproduce it anymore.
I will revert the temporary changes I had made here in our local branch and
keep an eye on it just in case it comes back. Will keep you posted if/when
I have more details.
thanks for looking into it.
regards,
-Yannick
