kubuntu ubiquity crashes at New Partition creating

[Vitovt]

Binary package hint: ubiquity

During installation on step 4. I choose create partition manualy. Edition and formating partitions works well. But just I press "New Partition" button - ubiquity crashes:
Traceback (most recent call last):
  File "/usr/lib/ubiquity/ubiquity/frontend/kde_ui.py", line 1463, in on_partition_create_use_combo_changed
    text = str(self.create_dialog.partition_create_use_combo.currentText())
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-6: ordinal not in range(128)

I tried ubiquity version 1.8.13 and 1.8.7. Linux Mint Elyssa (Based on Kubuntu Hardy)
