jmap.b.jMap property does not exist

What steps will reproduce the problem?
1. Use the following function: 
   $("#map").jmap({center:[27.586197857692664, -
84.17724609375],zoom:6}).addRss
("http://www.dep.state.fl.us/water/tmdl/js/TMDL_Basins3.kml", function(){})

What is the expected output? What do you see instead?
I expect between 1 and 3 shapes to be created on the map with the given 
kml file. The kml file is not rendered and I see an error in Firebug 
stating: jmap.b is does not exist (or something to that effect). 
jmap.b is used about 6 times (line 199, 268 are the first instances I 
think).
What version of the product are you using? On what operating system?
1.4 (08/08/2007)

Please provide any additional information below.
According to Firebug's Script tool, the jmap object does not have a 'b' 
property, however it does have a 'd' property...changing the 'b' to a 'd'
seems to solve the problem, but I'm not sure if it messes things up 
elsewhere.
