qtpbfimageplugin-qt6 needs recompile with latest abseil-cpp/protobuf
The current qtpbfimageplugin-qt6 package - 3.0-1 - is compiled against Qt 6.6 and does not work with the current Qt 6.7 as used in Arch. It needs a recompile against Qt 6.7 to work. Also note that this is a general requirement - it must be recompiled with every new Qt version like any other Qt plugin (e.g. qt6-imageformats).
