Bug#964867: crashes when clicking on something not a link in New Game menu

[Judit Foglszinger]

Package: monsterz
Version: 0.7.1-11+b1
Severity: minor

to reproduce:
New Game-> *click on something, that is not a link* -> *crashes*

For example I clicked into the upper left corner:

Traceback (most recent call last):
  File "/usr/share/games/monsterz/monsterz.py", line 2043, in <module>
    main()
  File "/usr/share/games/monsterz/monsterz.py", line 2038, in main
    monsterz.go()
  File "/usr/share/games/monsterz/monsterz.py", line 1288, in go
    iterator()
  File "/usr/share/games/monsterz/monsterz.py", line 1565, in iterate_new
    elif event.type == MOUSEBUTTONDOWN and narea >= 10:
TypeError: '>=' not supported between instances of 'NoneType' and 'int'


A quick fix would be to check if narea is None.
