Ahh, I see. Yes, I also see it sometimes, for those cases the "Mimic Chrome" workaround usually fixes it.

I assume is a side effect of abusive crawlers compounded with Dillo headers not being very common.

Very possible. I was too lazy to investigate.

BTW Thanks for all fixes, especially this one https://bug.dillo-browser.org/511/. Dillo (3.2.0) crashed quite often on my system because of this bug. I hope I will compile and test the new release soon.
