Comment 5 for bug 133937

It is not fixed in Gutsy.

I could now reproduce it, after adding the key 0x3714DD6A to my apt keyring.

It appears like the encoding of the key itself is invalid and software-properties-kde should handle this better (by ignoring it). At least KGpg displays the key desc "scrambled", while "apt-key list" displays it correctly.

I will attach the offending key, so that you can test it easily.

After "sudo apt-key add 0x3714DD6A.pub.gpg" I get the "Installer crashed"(?) dialog with the same traceback.
