Can you show the report from checking with the inputs switched?  I.e.
the result of "upgrading" from using libnotify to not.  That should
show us all the symbols which get added by turning on libnotify, which
would be useful to know.

That does sound promising.

We just need to make sure packages compiled against the newer library
will get a suitable >= dependency, which I think we can with a suitable
shlibs file, though I've never tried to do so before.

Thanks for looking into this - if it's actually possible to do, I'll
try to ensure it gets in before the freeze.

Cheers,
