Popup crashes for a certain cell

[yangvz]

The file was in chinese. To replicate the error, navigate to the cell starting with "Camera" and hit enter. All others cells pop up fine.

Could be that the text is simply too long, or something's wrong with unicode support.

It's something about the wide characters when the terminal window is too small. It worked fine for me initially, but then resizing the terminal window smaller forced the crash. I'll look into it when I get a chance. Thanks for the report!
