With luck, they'll have a firmware upgrade already available...

Yes, I was mistaken about this.  Although the code that checks the 
"Range:" header has not changed in a long time, it turns out that - 
in old versions of "RTSPClient" - we were silently ignoring "Range:" 
headers - like this one - that were malformed.  In our recent new 
"RTSPClient" implementation we started reporting malformed headers as 
errors - which happened to catch the bug in this camera server.
