[Bug 440764] [NEW] ttb: TypeError: 'tuple' object does not support item assignment

[happyhamster]

Public bug reported:

Binary package hint: ttb

Ubuntu version: Ubuntu karmic (development branch) Release: 9.10
Package: ttb 1.01-0ubuntu2

Expected behaviour: when right-clicking the forward button on a page
that has no more subpages, the first subpage is displayed. The same
event happens when using keyboard shortcuts (Shift+PageDown).

Bug: instead, when right-clicking the forward button, ttb freezes for a
few seconds, and the forward and backward buttons remain greyed-out.
After clicking the page-refresh button, things go back to normal.

How to reproduce: select a page with 2 or more subpages. Select the last
subpage. Right-click the forward button or press Shift+PageDown.

Terminal output:
user at karmic-test:~$ ttb
Traceback (most recent call last):
  File "/usr/bin/ttb", line 388, in on_button_press_event
    self.goto_neighbour_page (prev,sub)
  File "/usr/bin/ttb", line 298, in goto_neighbour_page
    self.page = self.model.goto_neighbour_page(prev,sub)
  File "/usr/bin/ttb", line 142, in goto_neighbour_page
    return self.goto_page (neighbour_page)
  File "/usr/bin/ttb", line 161, in goto_page
    page[1] = 1
