flow-fanout filtering broken

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use one instance of flow-fanout with a filter and one without a filter
2. Have each instance send data to a different instance of flow-capture.
For simplicity, flow-capture A gets the unfiltered data and flow-capture B
gets the filtered data.
2. View the filtered and unfiltered data captures with flow-cat

What is the expected output? What do you see instead?
I would expect to see the flows that match the filter in the data collected
by B, but they aren't.  If I run flow-cat | flow-nfilter | flow-report on
the unfiltered data collected by A, using flow-nfilter with the same filter
as one of the instances of flow-fanout, I see the filtered data reported. 
If I look at the data captured by flow-capture B, I see no data collected.

What version of the product are you using? On what operating system?
RHEL5, flow-tools 0.68.4.2

Please provide any additional information below.
This appears to have been a problem before with flow-tools 0.67:

Maybe the fix was overwritten?

Update: Tested the same filter with flow-capture and flow-capture works as 
expected
with the filter.
