I noticed that format_decimal implicitely asserts num_places > 0.
Using code like this
assert format_decimal(5.9, 0, "de")=="6"
generates the following exception:
======================================================================
ERROR: turbogears.i18n.tests.test_format.test_format_numbers

I attached a patch which should work for 1.1 also - unfortunately I can't confirm this right now because I do not have all the necessary modules for 1.1 installed.
