Hello Sebastian,

I implemented the Pdf filter using Poppler-qt4, as of now it is only for
text. It is *working* perfectly fine on pdf files with texts. :)

But there is a problem, I was working on the code which was few days old.
When I pulled the master today to merge it to my branch and push it to
repo, Calligra Word stopped working. :(
I guess there is some problem with this new code which I pulled. I compiled
the master itself, but even then when I'm launching *
/calligra/words/part/calligrawords* and trying to open some file (even if
Blank Document), it crashes. Giving this message in terminal:
http://paste.kde.org/398438/

Can you please see what is the problem. I tried recompiling my old source(
I pulled it some few days back) It was working fine. But the one I fetched
today is giving this error.

Thank you.
