blender crashed with SIGSEGV in tupledealloc.21729()

[Sasa Paporovic]

I have used morse-simulator0.6 to drive blender2.63a.

I have called from terminal

:~$ morse edit /usr/share/morse/examples/tutorials/tutorial-1-sockets.py

which gives a scene opening in blender.

Choosing a desk of the sceene

Desk_3.000

moving it arround with g + x or y or y and mouse moving and setting it some meters over the floor is the basis for this crasher.

Afer this I have only pressed severald times the z button.

That gives the crasher.

Steps to reproduce:

1. Install morse-simulator and blender in Ubuntu12.10 Quantal
2.Open an terminal and give:

morse edit /usr/share/morse/examples/tutorials/tutorial-1-sockets.py

3.See blender starting with the called scene.
4. Choose the Desk_3.000 and move it arround as described above.
5.Press several times z and see blender crashing.

Reproducability:

 Tested, but only sometimes reproducible(in addition try arround with the lender player -> pressing p for starting and esc for ending.

I have tried to verify the reproducing procedure I give above, but unfortunally I could not provce a crash.

[Sasa Paporovic (melchiaros)]

I have hit this a second time, in addition to the reproducing steps above I have started the blender player with p and quit it with esc.

[Sasa Paporovic (melchiaros)]

On Ubuntu13.04 Raring 64bit I have hit this with just closing the morse-simulator tutorial file

/usr/share/morse/examples/tutorials/tutorial-1.blend

which was openend direct with blender without any further usage of morse.

[Séverin Lemaignan (skadge)]

Based on the reporter's description, this is a Blender issue, not related to MORSE itself. Marking the bug as invalid for morse-simulator.

[Nazo (lovesyao)]

Morse Simulator is based on Blender Game Engine (BGE) but BGE was gone so I closed the bug as invalid
