In revision 1.16 of qscintilla.spec Rex has removed "%define scintilla_ver 1.73", but has not changed %description that is using scintilla_ver, making description look like this: "This version of QScintilla is based on Scintilla v%{scintilla_ver}." Apply to rawhide and F9.
fixed (only is rawhide so far... F-9 will see an update soonish)
