picture of "click multiple times on stroke recogniser icon"

Testing Environment
===============================
Host: qemuarm sato/sdk
Kernel: 
Image location: http://autobuilder.pokylinux.org/nightly/20121219-5/machines/qemu/qemuarm/

Steps
===============================
1) Boot up the qemuarm with sato/sdk image
2) Enter Desktop-->Utilities
3) click multiple times on the “stroke recogniser” icon(>5 times)

Observed Result
===============================
1) The number of matchbox-stroke processes is increasing and never release , this leads to memory leak;
root@qemuarm:~# ps | grep matchbox-stroke
  428 root      5436 S    matchbox-stroke
  436 root      5300 S    matchbox-stroke
  438 root      5300 S    matchbox-stroke
  445 root      5300 S    matchbox-stroke
  447 root      5300 S    matchbox-stroke
  449 root      2212 S    grep matchbox-stroke
2) On desktop, the white writing board becomes larger after clicking, and covers the icons.
Comment 1 Ross Burton 2013-02-14 16:43:58 UTC 
Fixed by removing matchbox-stroke.
