Comment 4 for bug 96201

I managed to recreate a similar bug on karmic, which looks like the updated version of the same root bug as this post from 2 years ago:

Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/softwareproperties/kde/DialogMirror.py", line 117, in on_treeview_mirrors_cursor_changed
    mirror = self.mirror_map[hostname]
KeyError: u'\u041c\u0430\u043b\u0430\u0439\u0437\u0438\u044f'

Steps to recreate:
1. boot karmic livecd and select Russian from the language boot menu
2. run software-properties-kde
3. select 'Other...' (russian equivalent) form the mirrors combobox
4. select a country title (a parent node, not an actual mirror url child, and not the expanding '+' - just the title itself)

Note: you may need to apply the fix for bug #464707 first, as it masks this bug by preventing the mirrors selection dialog from ever opening...
