Comment 14 for bug 87023

FYI, gksu (as of libgksu version 2.0.11) allocates a new pseudoterminal, runs sudo -v to acquire a token, then uses g_spawn_sync in the parent process once the authentication is successful. (This allows gksu to be executed with the 'Defaults requiretty' option, which is enabled by default on RHEL.) Obviously, this fix doesn't work properly with the tty_tickets option. I'm going to write another patch to try and address this issue.

Until then, I wouldn't be using the new libgksu in Karmic!
