Comment 1 for bug 184772

I can replicate this issue on Ubuntu 8.04 64bit. I also think it is something to do with 64bit and Python. I have no issues on a 32bit system.

aDesklets was installed from source, using Python 2.4.

Output when launching Calendar desklet:

./Calendar.py
Do you want to (r)egister this desklet or to (t)est it? t
Now testing...

in the top left corner of your screen), try `--help',
and see the FAQ: `info adesklets'.
