The recently reported issue with GRC in the Ubuntu 9.0.4 binary
installation for GNU Radio 3.2.1 has been fixed, and new packages for
64-bit architecture machines have been posted. New packages for
32-bit machines are being generated and will be posted soon.
To obtain the packages, simply perform a package update from either
Synaptic or via the command line.
The issue was not with GRC itself, but with how the GNU Radio
configuration file operation works when GNU Radio is installed in the
the /usr file hierarchy instead of /usr/local or elsewhere.
