thanks that already narrows down the issue.
can you please post the output of:
grep flags /proc/cpuinfo

and install blender-dbg and gdb.
then run
gdb /usr/bin/blender
set logging on
run
backtrace
disassemble

and attach output or the created gdb.txt to this bug.

found debian bug 599680
blender is built with sse2 enabled in i386, which is not always available.

for now a solution would be to rebuild the package for your machine so the build time feature detection (hopefully) disables it.
apt-get build-dep blender
apt-get source --compile --blender

blender (2.66a-1ubuntu1) raring; urgency=low

  * Resynchronize with Debian (LP: #1076930, #1089256, #1052743, #999024,
    #1122888, #1147084)
  * debian/control:
    - Lower build-depends on libavcodec-dev since we're not
      doing the libav9 transition in Ubuntu yet

If you try blender with glibc211 maybe will not working , try version with glibc27 ...

Blender 3D versions with with glibc211 not working just versions with glibc27 .
