Problem Description

I've been using master (version 4) as my daily driver until I updated last week and now code completion is crashing. This doesn't happen in version 3

It seem like the code completion thread is crashing after you run code from a cell.

Copying it into the console or running with F5 or F9 all seem to work fine.

What steps reproduce the problem?

1. Start Spyder Master
2. Copy this into and new file

# %% Code Cell
def function(x):
    return x

3. press Ctrl-Enter to run the cell

What is the expected output? What do you see instead?

After that Syder hangs for a minute and then spits out the debug seen below.

After the hang, Spyder is usable but there is no code completion

Paste Traceback/Error Below (if applicable)

Nothing in internal console.

This in the debug:

This was due to a 10mb+ history.py file. I got rid of that and now Spyder flys.
