Hi,

I'm getting a reproducible crash in ipython, but not sure what upstream it 
should belong to.

The crash happens with python 2.7.6/3.3.4, with readline 6.3.

Steps to reproduce:

- run ipython
- input some random char sequence that you never inputed (like 
"ae3r0gka03k0k23"), don't press Enter
- press "Up", followed by any key

Backtrace pasted here: https://paste.xinu.at/cg7/
Downstream bug report on Arch Linux: https://bugs.archlinux.org/task/39144

Any help would be really appreciated!

Regards,
Felix Yan
