--------------------------+--------------------------
 Virtual memory size of the shell increases by 20 Mb for each ten launches
 of the background control panel.

 To reproduce, capture virtual memory size at one second intervals;

 {{{
 while true; do
   echo $(date +%s.%N) \
     $(awk '/VmSize/ { print $2; }' /proc/$(pgrep -f jarabe)/status)
   sleep 1
 done | tee memory.log
 }}}

 Then open the background control panel, close it, and repeat ten times.
 Compare the starting VmSize to the ending VmSize.

 A graph to be attached.

 Cause might be Fedora 18, Python, libraries, or Sugar.
