Changes between Initial Version and Version 1 of Ticket #45354, comment 8

initial	v1
1	1	Confirmed that although, technically, neither glib2 nor gdkpixbuf2 depend on shared-mime-info, g_content_type_guess() does use it to guess mime type if present. If not, it doesn't fail but falls back to either 'text/plain' if it appears to text or 'application/octet-stream' otherwise. gdk-pixbuf2 will then fail to configure gio sniffing if shared-mime-info (including any previously cached mime data) is not available.

3		Since glib2 can't depend on shared-mime-info due to the creation of a dependency loop, this means not just gdk-pixbuf2, but any port that wants to use this gio sniffing facility, needs to have shared-mime-info in its dependency tree at run time. Both gtk2 and gtk3 have shared-mime-info as a run time dependency so this is covered in many cases.

5	5	Library dependency on shared-mime-info added to gdk-pixbuf2 and revision incremented in r126880 to ensure the presence of shared-mime-info when gdk-pixbuf2 is configured and run.
