I just fixed this error, that occurs if popplerqt4 can't be loaded.

Try installing Python-Poppler-Qt4 (different from python-poppler, which
is GTK-based) :-)

Make sure Python-Poppler-Qt4 is compiled and installed for the same
Python version as Frescobaldi.

Try this on a command line:

python

>>> import popplerqt4

If that yields an ImportError, popplerqt4 is not installed correctly.

I get the import error. But when building popplerqt4 I don't get error
messages, neither when installing

Strange!

Maybe your Python looks not in site-packages but in dist-packages.

You could try:

python setup.py install --install-layout=deb

in the python-poppler-qt4 install command

That solved it, thanks!

I had a similar problem, (neither frescobaldi nor python console able to load the package), even though the default installation directory was in my PYTHONPATH and the library and egg info were where they were supposed to be.

However, I kept and compiled the sources on a NTFS partition, where Linux usually has permission handling problems. I got the package to work after compiling on my ext4 home partition.
