   I'm getting a similar issue, but without requiring an external dependency. Figured I'd add my own reproduction steps. I've also included a screenshot which shows color information.

   The issue seems to be occurring any time I try to tab-complete a dict key when all of the keys contain a slash and have a shared prefix. This is occurring in cases where I'm using the names of a collection of files as keys in a dict. My workaround is to not use tab completion in those cases.

   I love this project and this tool by the way, use it every day. Let me know if there's anything else I can do to help with this.

   Steps to Reproduce

   For reference, the last sequence of keypresses was x, [, then <tab>

   >>> x["a/c"] = 1
   >>> x["a/c"] = 1

   I was about to open a new issue but i think it's the same as this one, so I'll post my issue here in case that can help.

   I'm working with numpy arrays, and i get a really weird crash when trying to create an integer array. Basically, I can create any type of arrays just fine, except when I want to create an integer array with either 2 or 3 as numbers (yeah, it's really weird).

   What works

   >>> import numpy as np 
   >>> np.array(['test1', 'test2'])
   array(['test1', 'test2'], dtype='<U5')
   >>> np.array([1, 6])
   array([1, 6])
   

   Doesn't work

   But if I try the exact same array as the second, but try to replace either number by either a 2 or a 3, i get a similar crash as people above :

   >>> np.array([1, 6])
