After looking at the code, I wouldn't necessarily call such a situation "normal" 
but it is guaranteed that if you see the "Unable to parse INFO message" that the 
content will be garbage. This is because the buffer is guaranteed to be 
uninitialized at the point that message prints. What's really strange is that 
there is a line of code commented out above that warning message that would 
populate the buffer with real content. This same line is commented out in the 
1.4 releases you mentioned, too, so I would expect you to see the same error there.

This message is printed if you are trying to send an INFO request with a 
Content-Type that is not understood by Asterisk.

"sip set debug on" will print all SIP messages that Asterisk receives and sends. 
  You can also try playing with the core debug level, but I don't know that it 
will necessarily help here.

Nothing that I know of, but you can check https://issues.asterisk.org to see if 
there are other issues that seem similar.
