Same here, but this time loading ipython qtconsole embedded in an app.
The code looks similar to this:
http://stackoverflow.com/questions/29421936/cant-quit-pyqt5-application-with-embedded-ipython-qtconsole/30068103#30068103

It's actually way more extensive, but it crashes when it tries to create
the kernel.

I used this workaround to "fix" it:
sudo mv /usr/lib/python3.4/lib-dynload/readline.cpython-34m-x86_64-linux-gnu.so /usr/lib/python3.4/lib-dynload/readline.cpython-34m-x86_64-linux-gnu.so.bkp

It works fine now.

Title:
  blender crashes on python code completion

Status in blender package in Ubuntu:
  Confirmed

Bug description:
  Release: ubuntu 14.10 64 bit
  blender version: 2.70a-2ubuntu3

  Open the python console with SHIFT F4, type a blender python class,
  e.g. bpy., and press CTRL BLANK for code completion. Blender crashes
  with a segmentation fault. The expected behavior is showing a list of
  attributes/methods of the python class.

  If you need more informations like gdb backtrace or logfiles, please
  have a look on this blender bug report:
  https://developer.blender.org/T43491

  We - that meens some of the guys discussing this bug - think it's a
  library compatibility problem which can be solved by a rebuild. As I
  found another segmentation fault - if you mark an object, press 'm' to
  move it to another layer, and click on the layer symbol - I think that
  the actual blender build on ubuntu is a little bit unstable.

  I reproduced both segfaults with an ubuntustudio 14.10 live dvd.
