GNOME Bugzilla – Bug 586858
file save as is broken in trunk
Last modified: 2009-06-24 18:29:16 UTC
In libgthumb/dlg-save-image.c, a null mime type is reported when using the automatic (determine by extension) mode, because the gfile/filedata functions do not currently report a mime-type for a not-yet-saved file. get_file_mime_type has content-type guessing based on extensions, gfile_get_mime_type does not. - Mike
Fixed now.
