If a translator mistypes a variable name's format, causing the string formatting to fail with a
ValueError, then the entire page will go down with a 500 error. That error should be ignored to prevent that.
Note: this is different than if the variable name itself is wrong. In that a case, a
KeyError is returned but this is already taken care of by https://github.com/django/django/commit/16bb9c594c
Pull request coming soon.
