Nuance Speech Server Errors on a header with a float value that end is '.'

It appears that Nuance Speech Server doesn't accept headers of the format:

Sensitivity-Level: 0.

It appears to be a valid format according to the draft RFC, but NSS doesn't 
like it.  NSS will accept:

Sensitivity-Level: 0.0

Confidence-Threshold has the same problem.  I assume that all float type 
headers will exhibit the same problem.  I modified apt_float_value_generate() 
in  the attached apt_text_stream.c to generate the second format.  I didn't 
look any other uses of that function to verify that I didn't break anything 
else.

What steps will reproduce the problem?
1.Set Confidence-Threshold to 0.0
2.The unimrcp client libs will format it to "Confidence-Threshold: 0."
3.Send the RECOGNIZE

From my logs which may be formated differently than your default:
