[Scribus] Can't print to file /path/to/foobar.pdf

[KS]

Hello,

I'm making a catalog for an exhibition (yes, again ;)) and wanted to see
how the document was progressing by creating a pdf. Right now I just
have text, some gradient boxes and 2 templates in that document. I tried
to export it to a pdf and it gave me an error: Can't print to file
/path/to/foobar.pdf

This doesn't have to do anything with file permissions as I'm in my home
folder. This machine is a Debian Unstable running 2.6.16-1-686 with
scribus 1.2.5.dfsg-2 installed on it.

I did an strace and got an error on the console:
~/tmp/attachments/cwott-eu$ strace -o debug-scribus-new.txt scribus
Can't find Plugin/usr/lib/scribus/libs/libpdf.so: cannot open shared
object file: No such file or directory

and the /usr/lib/scribus/libs/ shows me the following:
~/tmp/attachments/cwott-eu$ ls -al /usr/lib/scribus/libs/
total 868

If anyone wants to inspect the debug file, let me know I still have it.
The last time I was using scribus, it was 1.2.3 and the pdf creation was
working fine. Did something change with regards to libpdf.so?

thanks,
