Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

r57951
I encountered an crash after using a Rigid body. After several experiments I did not manage to precisely identify where the bug does come from. But I found the steps to completely reproduce the crash on my system.
I also found a strange thing that the crash somehow depends on the folder from which I open a file: If I open the file from the root directory (C:\delete_crash.blend), then the crash occurs in 2.67b and in r57951; But if I open the file from a folder (C:\test\delete_crash.blend), then the crash occurs only in r57951. So, perhaps this a Windows only bug.
Open attached .blend file. Press Shift+← to jump to first frame. Press "Remove" button on "Rigid Body Tools" panel on Tool Shelf. Press X and delete selected objects = Crash.

Changed status to: 'Open'
%%%Confirmed, the bug looks to be that Remove isnt removing constraints from the rigid body world.
See valgrind output, assigning to Sergej.

%%%Thanks for the report, fixed in svn r57987.
The behaviour of removing rigid bodies is different now, it will remove constraints as well.%%%
