Occasional crash when pressing "again" or "good"

[vegardholt]

Hello!

Sometimes when I press "again" or "good", Anki suddenly crashes.
I haven't notices a pattern to these crashes.'

This is the error log I get:

Error
An error occurred. Please start Anki while holding down the shift key, which will temporarily disable the add-ons you have installed.
If the issue only occurs when add-ons are enabled, please use the Tools > Add-ons menu item to disable some add-ons and restart Anki, repeating until you discover the add-on that is causing the problem.
When you've discovered the add-on that is causing the problem, please report the issue on the add-on support site.

It sounds like you downloaded the old version on ankiweb or 2.1.15.
The new version on github hasn't been uploaed to ankiweb yet.

That would explain it. I'll try downloading the newer one. Thanks!
