I also never wanted poppler instead of xpdf and never voted
for it. I doubt very much it would bring any advantage at
all, while the problems it caused are quite obvious.

I am a debian user myself. There was a time when my xpdf
segfaulted for a certain pdf. I reported the problem to
Derek and then we found out that the problem happened only
with the binaries provided by debian. Of course it's not
hard to guess what was Derek's reaction then.
