This message usually appears when an OMRaster can't find the image
file, or it's still in the process of downloading it from a URL.

I'd check what the defaultIconURL property looks like. The
CSVLocationHandler is supposed to ignore empty or whitespace entries,
but it might be getting a value from the new properties file that is
causing it to choke a little. If you are setting that property, make
sure the value represents a valid URL (using '/' instead of '\' on
windows, etc).

Hope this helps,
