HLS transcode (and likely others) give NULL string db error

[beirdo]

2012-03-27 19:15:28.759108 E [15286/15286] CoreContext mythdbcon.cpp:648 (exec) - Original query failed, but resend with empty strings in place of NULL strings worked. 
DB Error (MSqlQuery):
Query was:
INSERT INTO inuseprograms  (chanid,         starttime,  recusage,  hostname,   lastupdatetime, rechost,    recdir) VALUES  (?,       ?, ?, ?,   ?,   ?,   ?)
Bindings were:
:CHANID=0, :HOSTNAME="mythbe", :RECDIR="", :RECHOST=NULL, :RECUSAGE="transcoder",
:STARTTIME=2012-03-27T19:15:28, :UPDATETIME=2012-03-27T19:15:28
Driver error was [2/1048]:
QMYSQL3: Unable to execute statement
Database error was:
Column 'rechost' cannot be null

The program works as expected after trying again with "", essentially. A minor inconvenience that messes up the logs, not terribly important.
