I upgraded to openSuSE 13.2 a few days ago. The lilypond editor “frescobaldi” aborts immediately after displaying its splash image with this error message:
> RuntimeError: the sip module implements API v11.0 to v11.1 but the popplerqt4 module requires API v10.1
Is the current version of popplerqt4 compiled against a recent enough version of sip?
And which versions from which repos do you have installed? (python-poppler-qt4 does not use/need python-sip at all, but python-qt4 does which is used by python-poppler-qt4)
rpm -qi python-poppler-qt4 python-qt4 python-sip
The versions of python-poppler-qt4, python-qt4, and python-sip shipped with openSUSE 13.2 are definitely compatible with each other.
Remove the Factory repo immediately, as I already wrote in the other thread, and run “sudo zypper dup” to completely switch back your system to 13.2.
Then frescobaldi should work.
