According to upstream KDE bugzilla, KPDF does not use poppler anymore. http://bugs.kde.org/show_bug.cgi?id=107793#c16 Furthermore using poppler seems to be the cause for KPDF to experience major memory leaks - big enough to make a system unresponsive (which also happens to me). Solution: - removing poppler as dependancy of KPDF
Kindly review http://bugs.gentoo.org/page.cgi?id=fields.html#bug_severity
I did. And thought that memory leaks that are big enough to make a system unresponsive to the extent that it isn't able to refresh htop in half an hour, qualifies as "major". I'm really sorry if I misunderstood the term "major memory leak", it was not my intention to draw attention to this bug against Gentoo's bug policy.
KPDf never used Poppler. The patch stemmed from Ubuntum, but had too many issues, so last but not least it has been removed, so the latest 3.5.5 and 3.5.6 revisions don't have the patch applied. Diego missed to remove the dependencies, though. Your memory leak problem will likely be bug 164248, otherwise it's a bug in KPDF.
*sigh*
uh, wrong bug, still need to fix the dependencies...
Thanks for the explanation. And, yes, as far as I can see from today's portage sync, the dependancy is still in both 3.5.5-* and 3.5.6.
Apparently, the meta info plugin uses poppler, even if KPDF doesn't.
