Bad request after multiple filter changes

Using plugin ver. 2.3.4
When displaying the activity log, if I change the filter multiple times, in my case, only changing the Types field, leaving the other fields on all values, the requested URL is malformed and the server returns a 400 Bad Request error.
I have tried this on two different browsers (Firefox and Opera).
Clearing the browser cache does not resolve the problem.
However, logging out and logging back in does seem to temporarily resolve the problem.

The malformed URL is a very long string, similar to:
