Details:
I have an issue that looks somewhat similar to
http://savannah.gnu.org/bugs/?47991.
I get random "invalid multibyte character" on a desktop file
(https://git.gnome.org/browse/shotwell/tree/misc/shotwell.desktop.in.in) while
trying to update the pot file in shotwell.
Valgrind shows some invalid reads in desktop_parse:
