You mean you've just opened the NTP servers configuration dialog and right-clicked on the "0.fedora.pool.ntp.org"? Because I cannot reproduce the traceback like this way.
Comment 17 Vratislav Podzimek 2012-11-28 12:19:54 UTC 
Patch for testing path validity was sent to anaconda-patches.

Yes, in the dialog for the list of NTP servers, I clicked on the 0.fedora.pool.ntp.org to edit it. What must have happened is I started editing the host name as blanked and it was then when I hit the right mouse button and the crash occured. It seems the event that occured was a validation attempt on the string in that entry. Since I right clicked when it was empty, it was attempting to validate an empty field.

Right-click to the text entry shows me a context menu, but if one right-clicks on some other item, it stops editting and that might cause the traceback. However, the proposed (and now also pushed) patch seems to be fixing this issue. The other problem is that even an empty "hostname" is accepted, but that's another story. See bug #865869 for more information about that.

Going over old  anaconda bugs. I fiddled around in the NTP screen for a while and couldn't produce anything like this, so it looks like the fix worked. Let's close this out.
