Another thing: even if the registry on file is incomplete or nonexistant, and
writing the registry failed for whatever reason, the in-memory registry should
still be correct. gst_init() it should read the registry cache into memory if
it exists, and then compare it against the available plugins, to see if there
are plugins it doesn't know about yet, or that have been removed, or that have
changed since last inspected. If there is a discrepancy between the registry in
memory and the files available, it will try to update the registry in memory.
Lastly, if there were any changes, it will try to write an updated cache to
disk, so we don't have to do the whole re-inspect dance on the next gst_init()
in another process.

What seems more likely to me is that something went wrong during plugin
inspection and the plugin got "blacklisted" (which happens when plugins crash
during inspection or can't be loaded for whatever reason).

There's bug #648010 ("Better handling of blacklisted plugins: re-scan
occasionally, store reason for blacklisting") about that.
