FreeTDS not giving any results

Hi,

I have a python script that uses pymssql 1.0.2, that in turn uses
FreeTDS 0.91, connecting to a MSSQL 2008 server. It used to work, but
now I don't get any results. The FreeTDS log (below) show the data is
received, but it's not processed for some reason. I did some code diving
and printf debugging, and dblib.c sets the results_state to empty
because of a TDS_COMPUTEFMT_RESULT (line 4698 in dbsqlok). Does anyone
know why this is happening?
