Short description of error
Just open the file and try to go in edit mode. On my system it continuosly crashes.
If you disable the skin modifier, it doesn't crash. Maybe Crash report T59894 is also related to the skin modifier, since the complain was about an armature which was generated by that modifier. That's why i tag this report with "modifier".
