Exception in Pycharm when working on django templates

I'm working in Pycharm Community Edition on a Python Django HTML template file, and when I type 

   {% 

Codeivate breaks, with the exception provided below.

{% is the start of a special template keyword, i.e. {% for x in y %} or {% if x %}.

This only happens the first time I type it after opening PyCharm. It doesn't happen again until I've restarted PyCharm, I think. Log output at the link below:
