hugin: cherrypick fix for segfault on empty XDG_DATA_DIR#204740
Conversation
Hugin segfaults if the environment variable XDG_DATA_DIR is unset (rather than being the empty string). Upstream has committed a fix in edfddc6070ca6d4223d359fb4b38273a5aed2f2d but has not released it (hugin releases are *very* infrequent). Let's cherry-pick the fix since it might be a while before they manage another release.
