First of all, thanks for the very detailed report - it's very nice to
see complete reports with all information.

This is a known issue (I'm loathe to call it a fetchmail bug though,
because basically, the server sends invalid data and it's the server
that needs fixing), but I think Gentoo are actually patching that - I
fear fixing it in 6.3 though as people might then see garbage and
complain about it.

I will fix this for the next major release though.
