Comment 5 for bug 791622

glib.get_system_data_dirs is undocumented in documentation of pygobject. However, glib.get_user_data_dir exists since pygobject-2.18, so I assumed glib.get_system_data_dirs would also be present since 2.18 (Functions in normal glib exist since glib-2.6 according to its documentation)

Maverick has glib-2.26, but pygobject-2.21. Apparently glib.get_system_data_dirs doesn't exist yet in pygobject-2.21. Packaging such an old version of pygobject is weird imho, but Shuttleworthless probably doesn't give a damn, so I'll fix it soon. (I know ranting is undiplomatic, but I do it anyway ^_^)
