[osg-users] Terrapage loader and bad data?

When loading certain (many) terrapage files I notice that there are a 
lot of failed calls to getData. It seems as if it's often trying to read 
beyond the limits of the buffers that it has. For example it constantly 
calls "throw 1" in functions like:
trpgMemReadBuffer::GetData(char *ret,int rlen) after failing a 
"TestLimit" call.

I'm curious about this. These exceptions are obviously being caught and 
the loader recovers (the terrain does load) but I'm not sure what these 
exceptions mean. Do they mean I'm loading a terrain that's not of a 
version that the loader understands? Does it mean that the data in the 
terrain is formatted badly?

Anyone have any insight?
