Segfault when creating a pocket operation from saved sketches

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a rectangle sketch
2. Make a pocket operation with it
3. save the cad document
4. open the same document
5. try making another pocket operation involving the original sketch

What is the expected output? What do you see instead?
It segfaults when you leave the make pocket operation window.

After a save sketches which are not already in pocket operations, don't seem to 
be affected.

If you delete the pocket operation and then make another one it still segfaults.

If you delete the pocket operation. Save and then reload the file, then make 
another one you seem to avoid the segfault.

What version of the product are you using? On what operating system?
I have built it from source latest change 17th may, on Ubuntu 10.04

Please provide any additional information below.

I have tried to get something useful out of gdb, but am not competent enough to 
do so, would be more than happy to try if I had some idea of how to get useful 
symbols in there.

I have fixed this now, by simplifying operations so that sketches are not 
children of them any more.
