Wow. Tinycore is a nasty distribution to do development on...

Not really - you start from a very small, well-known base. You are very sure what you add and so you avoid the maze of inter-related dependencies common to most large distros...

This is rygel idling because it cannot find its plugins. I found that
the solution is to install shared-mime-info-locales (which depends on
shared-mime-info, maybe this is enough). If you then run into the
problem of

So, rygel installs its own plug-ins and then cannot find them :) I added shared-mime-info and shared-mime-info-locales and this problem disappeared.

undefined symbol: gee_abstract_map_remove, find the two places in the
media-export plugin source C files and replace remove with unset.

I patched gee_abstract_map_remove -> gee_abstract_map_unset in:
rygel-0.4.2/src/plugins/media-export/rygel-media-export-recursive-file-monitor.c
rygel-0.4.2/src/plugins/media-export/rygel-media-export-root-container.c

..but then I got this:
