Comment # 1 on bug 907982 from Dominique Leuenberger

I don't know - but I don't trust darktable:

        datadir = "/usr/share/darktable", '\000' <repeats 12 times>,
"`@\224\002\000\000\000\000\370\000\000\000\000\000\000\000\t\000\000@\000\000\000\000yN��\201\177\000\000\000\000\000\000\000\000\000\000`@\224\002\000\000\000\000\b\206\222\002\000\000\000\000\260WU\001\000\000\000\000\260WU\001\000\000\000\000\236���\201\177\000\000\260WU\001\000\000\000\000\220\360\\:\377\177\000\000\000\000\000\000\000\000\000\000\177\067\246\262\201\177\000\000@\022F\001\000\000\000\000PYU\001\000\000\000\000\000\362\\:\377\177\000\000\004\000\000\000\000\000\000\000\250\360\\:\377\177\000\000p��\262\000\000\000\000`@\224\002\000\000\000\000.",

=> I very much guess there is an invalid call to some glib function that does
not bring a null sentinel.

datadir as is looks corrupted
