When choosing JPEG from the Save As dialog, it defaults to .jpe extension instead of .jpg or .jpeg. The filter used is "JPEG-Bild (*.jpe *.jpg *.jpeg)" Reproducible: Always
This is not kolourpaint specific. It's handled by the kdelibs class KFileDialog - reassigning. Still, I can not reproduce on my openSuse 13.1 system. The shared mime database file /usr/share/mime/image/jpeg.xml contains the extensions in the following order: <glob pattern="*.jpeg"/> <glob pattern="*.jpg"/> <glob pattern="*.jpe"/> I assume this order is the reason why here I always get .jpeg as default. I have no idea how windoze gets the mime types
Saves as .jpeg in Frameworks 5.45.
