Dear Maintainer,

When I use this app to choose a mirror, or try to select

* Officially supported (main)
* DFSG-compatible Software with Non-Free Dependences (contrib)
* Non-DFSG-compatible Software (non-free)

The program simply does nothing.
The mirror i've selected isn't changed in the combo box
The check boxes aren't marked

So, the program is not utilizable for it's purposes
I've seen this problem around for a long time, and i guess this was solved in
squeeze.
But I have the same problem in wheeze again.

I'm a developer, but I don't have experience with Debian.
May I could help if you tell me how

Thank you

I tested this and got the same results as the reporter. When the
checkbox is clicked for "Officially supported (main)" the checkmark
appears briefly then goes away. Below is the debug output. The lines
after the gpg lines are repeated each time the checkbox is clicked.

$ software-properties-gtk -m -d

Regards,

reproduce it on my current system. I'll check again on my
older system later this month or next month.

Note: My old system uses a mirror on localhost, my new
system uses an official mirror.
