The error message that I get when trying to compile kbibtex from its git repository (checked out on 5 January) is attached. Reproducible: Always
Created attachment 96468 [details] error message
Compiled for me, but I added an extra #include statement on QRegExp. Please test and confirm commit c68189816a5e2779c998: http://commits.kde.org/clones/kbibtex/thomasfischer/kbibtex/c68189816a5e2779c998
thanks, now it's building again as it should
