Greetings,

Thanks for the new release.
I have upgraded my Ubuntu 9.04 64bit packages from 3.2 to 3.2.1 and I
get an error when I try to execute grc. First I thought it was
something with the flow graph it was trying to open so I deleted my
.grc file but I still got an error:

<<< Welcome to GNU Radio Companion 3.2.1 >>>

Grc in version 3.2 was running fine yesterday.
I have also successfully built the 3.2.1 source code earlier today on
a different machine running Ubuntu 8.10 64bit where I had no problems
executing grc.

Any hints appreciated.
Cheers

This may be a problem with the custom grc.conf installed in
/etc/gnuradio in the binary packages. Thanks for the report; we’re
looking into it.
