gnc.gui:ERROR:gnc-icons.c:96:gnc_add_stock_icon_pair: assertion failed: 
(pixbuf1 && pixbuf2)
fish: 'gnucash' terminated by signal SIGABRT (Abort)

I think this error is caused by gdk-pixbuf, which uses XDG mime-info
database to query file types.  Install the 'shared-mime-info' package
to activate the 'xdg-mime-database' profile hook should make it works.


To actually fix this package (and some others) we can:

- Wrap them with shared-mime-info in XDG_DATA_DIRS or propagated it.

- Make sure 'xdg-mime-database' always run if glib applications are
  there even without shared-mime-info referenced by profile.  
  IIRC, this was suggested by ludo, but I ignored, now patch sent :-)
