Ok, thanks. I had some strange usage of those two libraries as well, but
didn't think much about it. I probably had them installed with some
other application (like the GIMP). But since they are available from KDE
on Windows it's simple enough to install them as well.

Yes, they are supposed to work. I think I had a similar problem, but I
think you won't be able to confirm that because MinGW doesn't come with
a dll dependency walker. In my case, this problem didn't come from QtGui
directly (as used in TW). Instead, poppler-qt4 used an incompatible
version of QtGui - don't ask me how this could happen. In any case, the
problem was solved for me by reinstalling (at least) poppler-qt4 and
poppler from a different server (the one that was broken in my case was
a french server). If this doesn't help, try reinstalling the rest of the
libraries, and probably rebuilding TW to be on the safe side.

If this still doesn't work: the dependecy walker can apparently be
downloaded at http://www.dependencywalker.com/. It's not an easy tool to
use (it's intended for hard-core developers ;)), but if you see a red
QtGui.dll under libpoppler-qt4 on the left which - when you click on it
- displays a single red line on the right giving the function you posted
(_ZN8QPPaiter9drawImageERK7QPointFRK6QImage) it's probably the same issue.
