Hi,
I came across this pop-up error when I want to change the default shortcut of spyder27 in the conda environment of python 2.7. It seems simple to modify certain number of lines in the code. However, I am new to the development issues so I don't know how to solve this.

What steps will reproduce the problem?
I just simply open my spyder27 using command line, go to Preferences -> Keyboard shortcuts and do the modification. The error shows when I press the new shortcut before I select 'ok'.

What is the expected output? What do you see instead?
Please give me any advice that I can change the default shortcuts. Thanks!
Please provide any additional information below
I tried that in my python 3 environment and it works fine.

Thanks for reporting. @csabella, could you take a look at this one? This error appeared after your PR #6092.
Sorry. A stupid but quick question. Since I found this issues seems solved on #6251 , should I do anything on my end so that I can modify the shortcut normally?
@Gabrielvon Release 3.2.7 with the fix in it should be out before the end of the month. If that's too long to wait, you can try to edit the spyder.ini file directly, but that's not really recommended. Although, if you mess it up, it is recoverable using spyder --reset. Search for spyder.ini on your system. Open it in Notepad, or some other simple text editor (not Spyder and not Word), and search on shortcuts. Hopefully, you'll find the shortcuts you want to modify and you'll be able to change them as you wish.
@csabella Awesome! Perfectly solved my problems. Thanks a lot!
