Yeah, you are right. I hacked the related code a little bit (see below)
to see what gdk-pixbuf actually does and it doesn't make much sense. In
the strace output, it attempts to read the cache and fails (wtf?). I
couldn't find any link to cache dependencies in the GDK docs.
When I do the same on a PC where shared-mime-info is installed, I see
some activity around mime.cache.
stat("/usr/share//mime/mime.cache", {st_mode=S_IFREG|0644, st_size=139316, ...}) = 0
Seriously? Why does it open the mime cache?
Some internet references indicate that one might rebuild a pixbuf
loaders cache with the command
gdk-pixbuf-query-loaders > /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache
But when I try to install apt-get install libgdk-pixbuf2.0-dev then it
pulls the shared-mime-info package as dependency which makes the
investigation pointless. But why, seriously, does it do that?
And what's the problem with missing mime cache again? Questions over
questions... :-(
