   Ah OK.

  I did't know  CTT requires the DMS to serve some particular test
media. I thought it could be anything. It does however tries to find
some particular 'type' of media for many tests so could it be that
rygel is unable to handle some particular SearchCriteria (correctly)
or unable to extract the metadata (especially DLNA PN) for the media
in question and CTT searches the media through the missing metadata?

 Cool! You could either file bugs for the test cases causing the crash
with rygel console log and gdb backtrace attached (do run with
G_DEBUG=fatal-criticals if you see any CRITICAL messages on the
console) or (if you want to be even more helpful) you could dig issues
and submit patches through bugzilla or some public git repository.

  Just use the latest stable version of ALL libraries, especially
gupnp* and gssdp.

   Ah, interesting. I just wonder why we never encountered this issue.
To get some folder/file(s) exposed in the root container, you can use
the D-Bus APIs of MediaExport plugin.

   I do want to share the number of passing and failing tests and
their references but we haven't been able to run the tests for a while
due to some network issues and us being busy with some other stuff.
