[mythtv-users] mythfilldatabase getting bad start date message from SD

Mythfilldatabase has been running very slowly for me for a while. I
finally figured out why this is so. From my second or third request
for listing data, I have been getting the following error message in
the returned data:

The startTime you specified 8T05:00:00Z is not in a valid format, and
has been corrected to a default value. 

The default value is, of course, now. This means I have been fetching
all data, typically several times, for each mythfilldatabase run. I've
checked the post file that is handed to wget, and also captured the
data traffic leaving my site, and the startTime value is perfectly
fine, as seen in this capture of the reassembled stream: 

0390  73 27 3e 0a 3c 73 74 61  72 74 54 69 6d 65 20 78   s'>.<sta rtTime x
03a0  73 69 3a 74 79 70 65 3d  27 78 73 64 3a 64 61 74   si:type= 'xsd:dat
03b0  65 54 69 6d 65 27 3e 32  30 31 30 2d 30 31 2d 31   eTime'>2 010-01-1
03c0  38 54 30 35 3a 30 30 3a  30 30 5a 3c 2f 73 74 61   8T05:00: 00Z</sta
03d0  72 74 54 69 6d 65 3e 0a  3c 65 6e 64 54 69 6d 65   rtTime>. <endTime

The interesting thing is that the tcp packet is split into two IP
datagrams, the second's payload starting right at 8T05:00:00Z 

So, a refresh of today's or tomorrows data works fine, but when I try
to grab the data from more than 1 day ahead, I get this error, and a
full dump of all listing data. 

So now I'm stumped, It looks like the error is at the SD end, but I
have the feeling that this started either at the time I upgraded my
systems to lenny or myth to 0.22, but I can't say for sure. However,
the network capture looks fine, so it couldn't be an application
error. 

Has anyone else noticed anything like this. You can tell if you check
the output of mythfilldatabase and check if the 'Clearing data'
messages show the correct dates.
