31942	SafeExceptionReporterFilter does not recurse into dictionaries with non-string keys	Jeremy Lainé	Jeremy Lainé	"SafeExceptionReporterFilter has provisions for recursively cleaning settings by descending into lists / tuples / dictionaries - which is great! However, recursing on dictionaries only works if the keys of the dictionary are strings.

For instance it will fail to sanitize the following example:

`SOME_SETTING = {1: {'login': 'cooper', 'password': 'secret'}}`

The reason for this is that `cleanse_setting` starts by trying to apply a the `hidden_settings` regex to the key before attempting to recurse into the value:
