Since 0.23.3, Shotwell uses gettext also for translating its .desktop files. With gettext 0.19.7 as present in F23, this fails for the Keyword= entry, leaving some binary garbage in that line and resulting in an invalid .desktop file. With gettext 0.19.8 this works as expected. So, would it be possible to update gettext in F23?
For the record, the bug that hits Shotwell's .desktop file is this: http://savannah.gnu.org/bugs/?47991
