I believe that this is ultimately a regression caused by the fix for bug 756920 (ubiquity r4693). In order to try to ensure that the boot loader choice was recorded in debconf in every possible code path, this was done in exit_ui_loops as a sort of "finally" handler. However, exit_ui_loops is only supposed to do frontend interaction, and (as this bug demonstrates) it isn't safe for it to attempt to talk to debconf. I think a correct fix would move this out of exit_ui_loops again and try to find a safer way to fix the original bug.
