unity-panel-service leaks memory

Every day of uptime, the amount of memory unity-panel-service has reserved increases by ~80 MB.

After six days of uptime of this Desktop computer, I end up with:

VSZ RSS TTY STAT START TIME COMMAND
899184 495224 ? Sl Jun18 81:23 /usr/lib/unity/unity-panel-service

When I run strace on the process it turns out that it accesses /etc/localtime as well as files below /usr/share/zoneinfo/ a lot (multiple accesses per second). I should point out that I have several places configured in indicator-datetime's world-clock feature, so this may actually be a bug in indicator-datetime...

This may be related to bug #779185.
