[poppler] poppler really slow when reading some documents

1st test
qt/test-poppler-qt /tmp/serialata10a.pdf

the first page ist displayed within a second, switching to other pages
is fast, too

2nd test
Sorry, but I can't run the QT4 tests, because I haven't qt4 installed
yet and it is not available for my distribution.

3rd test
glib/test-poppler-glib /tmp/serialata10a.pdf

nothing is displayed, 100% CPU usage

Yes, it doesn't work. But this depends on the fact, that kdegraphics
3.5.0 has only "theoretical" poppler support. Something is linked
against poppler, but the xpdf stuff and the goo lib is built as well
(even if the project is configured --with-poppler) and used (as seen
in gdb).

The glib test app works in the poppler 0.4.3, but eats 100% CPU in CVS
version (during the print_index function, which isn't in the 0.4.3):
