Title:
  indicator-datetime-session severely leaks memory

Status in The Date and Time Indicator:
  Invalid
Status in “geoclue” package in Ubuntu:
  Fix Released
Status in “indicator-datetime” package in Ubuntu:
  Incomplete

Bug description:
  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:
  open("/usr/share/zoneinfo/Europe/Paris", O_RDONLY) = 14
  fstat(14, {st_mode=S_IFREG|0644, st_size=2945, ...}) = 0

  close(14)                               = 0
  munmap(0x7fd1a6bd9000, 2945)            = 0
