indicator-datetime-session severely leaks memory

After the most recent update to 0.3.91-0ubuntu1, indicator-datetime-session's memory increases at a rate of ~5MB/s, rendering my system unusable in a couple of minutes. Any advice on how to debug this issue? The service is always respawned after I kill it, making it impossible to directly run it in a terminal -- is there a way to prevent that? The issue persists even if I switch off the date display in the indicator bar. If I do an strace to the running process, the following seems to be repeated in an infinite loop:
