[BUG]When I set a global variable in my code,then jedi will crash

[yllgl]

my code is as follows: global variable_a variable_a=[] variable_a.append(somthing)

when I typed variable_a.append, Then "plugin_host has exited unexpectedly, plugin functionality won't be available until Sublime Text has been restarted" will occured. I don't know why.

My Jedi version is v0.13.4. And windows 10 64bit st3 Build 3176
