Seg fault during animation rendering

Description of problem:
I'm running FC4T3 using blender from fedora extras. I was running through the blender documentation doing the "Your first animation in 30+30 minutes". At the end of the "posing" section (the seond to last) one is instructed to view the animation by doing Alt-A. Doing this causes blender to seg fault.
I ran it under gdb and got this info
Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1208596800 (LWP 5286)]
0x0393ca25 in __gnu_cxx::__pool<true>::_M_reclaim_block ()
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.do blender animation tutorial
2.set up armiture and skin and poses for 40 frames
3.run Alt-A to view animation.
Actual Results: seg fault
Expected Results: animation preview
There will soon be a blender-2.37-2 in the FE4 repository. If you're impatient
it is presently here:
Would you please retest with this version and report whether the crash still occurs?
On Fedora Core Development, "yum install blender" installed an old
blender-2.35-1, which causes trouble here while trying briefly to get a more
detailed traceback. Before I'm going to switch to FE4, I see this during start:
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
'import site' failed; use -v for traceback
No installed Python found.
Only built-in modules are available. Some scripts may not run.
And this in gdb:
Program received signal SIGFPE, Arithmetic exception.

Inside Blender, the entire GUI flickers heavily. Widget colouring is corrupted.
Menus appear transparent. Close to unusable. Needs a rebuild. It was last built
With blender-2.37-2, I see the same heavy GUI flickering. Hence I can't be of
any help trying to get a more detailed backtrace. One observation, though.
Loading example files and Alt+A gives animations and doesn't crash. Makes me
assume it's not a general problem, but think that the 2.35-1 binary from Dec
2004 was also too old for FC4T3.
Can you update to blender 2.41 and try again.
I'm doing some FE bug triaging, perhaps this bug should be closed due to lack of
the original reporter, esp. since you cannot reproduce it?
OK, I hope, the reported bug may fixed in the current version of blender. So I
will close this bug.
I the issue persist, the bug may be reopen.
