Javascript errors/warnings when creating a connection

[GoogleCodeExporter]

I try to update JsPlumb from 1.3.10 to 1.3.15. But now I got Javascript 
warnings (logs) and errors. This was not the case with 1.3.10.  

I can reproduce this also on your demo site:
http://jsplumb.org/jquery/flowchartConnectorsDemo.html
When I create a connection, we've got the warning "TypeError: K is undefined". 
(see attachment 1)

On my application, in the same case, I got "jsPlumb function failed : 
TypeError: o is undefined" (see attachment 2). 
Not sure if this is the same problem. 

Ps. I created the stacktrace with console.error(msg) instead of console.log. 

System: Firefox 16.01/Win 7/SVG/jQuery 1.8.2/jQueryUI 1.8.24

I've got the same error on Firefox 15.01. This issue is not related to issue 
283. It's maybe related to issue 285.

HI,

I can reproduce the error on Mac OS X with Firefox 15.01

I will try to explain the use case more clear, and I found a shorter use case:
1) goto http://jsplumb.org/jquery/flowchartConnectorsDemo.html
2) open firebug and the enable the console log
3) drag a line between node 1 and 4. (= drag from the right blue endpoint of 
node 1 and release the mouse on node 4) 
4) the console reports: "jsPlumb function failed : TypeError: K is undefined" 
(on Firefox 15.01)

note!: When dropping the line on the green endpoint, no message is reported. So 
drop it on the node itself (the 'maketarget')
