Yes, but that's a separate problem from the essence of the bug report.
Regardless of the lack of progress on bug #18913, the information
provided by an assert being triggered is unhelpful and inadequate.
That aside, I can't see how the two assertions suggested in #18913 could
trigger the message I saw. I'll maybe have a look at the actual patch
sometime when I'm less tired.
