I still can't reproduce this myself. I tried selecting 'Epson' for the manufacturer, then selecting the first model in the list and holding down the down-arrow key until the last model was selected. 'Printer', 'PPD', and 'Driver' buttons were all set, and I tried with LC_ALL=ru_RU.UTF-8.
I hope the Ubuntu package maintainer manages to reproduce this bug and discover the cause..
