Hi:

I have spent some time looking at this.  It doesn't appear to be
an instance of an obvious error however.

I am also having great difficulty debugging this, for reasons
probably all too familiar to Michael.

At the moment test-gail-gnome is failing for me, but there are
other config problems that are likely to blame there.

I found and patched a problem in libspi that looked like a
candidate but I believe this was coincidental.
