- Short description of error ---

Modifying existing texture node groups has the tendency to crash a lot, especially when dealing with complex, nested node groups and when manipulating node connections adjacent to the group's input/output nodes.

This happens both on 2.68.0 from my distribution's repositories and on 2.68.4-r59974 which I compiled myself.

Please note that on a different .blend file I was getting a crash in an entirely different place so there is probably something wrong with group nodes' bookkeeping rather this particular codepath. (In other words - this crash may be just a symptom, not the cause.)

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

Open the attached blend file.
Try rapidly clicking on the socket dot in the Group Output node; if that fails try disconnecting are reconnecting two nodes and then try again.

This can also be easily reproduced from scratch - create a few nested texture groups and try editing them.%%%

%%%r59995, unfortunately it is not fixed.

Here is another .blend file that crashes: http://www.pasteall.org/blend/23983

Just add a new Math node, click on the empty socket in the Group Input and drag it to one of the sockets in the newly created Math node as if you'd want to connect them.%%%

i append a video, that shows the crash.%%%
