Dear maintainers of subtitlecomposer,
The package subtitlecomposer doesn't build from source if the package
"qt5-qmake" is installed. If this package is installed, the
subtitlecomposer's build system will use the Qt5 QMake instead of the
Qt4 QMake, but subtitlecomposer/KDE is incompatible with Qt5.
This can be fixed by either patching the build system to use the
specific executable "qmake-qt4" instead of the generic executable
"qmake" or by simply adding a "Build-Conflicts" entry for "qt5-qmake".
Thank you for maintaining subtitlecomposer and in advance for fixing
