Bug Description

This issue started since 22.04, but only after upgrade to 22.10 I've managed to cleanly catch it.

My son's user account is configured for 1.5 hours daily. After the migration to 22.04/10, the session time that timekpr reports goes to 00:00 and he stays logged in with no apparent actions taken by the timekpr daemon (unlike previous versions where he was force logged out). To better reproduce it, I've decreased his daily limit down to 3 minutes and upon him logging in, following was printed in the /var/log/timekpr.log:

after that timekpr keeps waking up every 3 seconds with fields tltd and tlrow decremented on every isUserActive call (I assume these are in seconds). After about 120 seconds, it raises a second similar error:

and this is it - session never kicked out and continues to run until he logs out himself. In the logs, timekeeper continues to report him, but no actions are taken:
