Sugar crashes touching the screen with 5 fingers

[humitos]

Steps to reproduce it:

1. Start Sugar - it will show the Home View
2. Touch the screen with 5 fingers, forming a circle and move them to the centre of the screen

Issue:

Sugar crashes and it is restarted

Expected behaviour:

Not to crash.

Environment:

13.1.0 - os5 - XO 1.75

Comment:

If I comment out GObject.idle_add(setup_gesturehandler_cb) on /usr/bin/sugar-session and I restart Sugar this does not happen anymore.

Sometimes I get this on the shell.log

Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/jarabe/desktop/favoritesview.py", line 458, in __leave_notify_event_cb
    if self.palette.is_up():

I cannot reproduce this on an XO-4 B1 with 13.1.0 - os5

XO-4 B1's only can track two fingers by default, so this is an issue which only affects touchscreens which can track more points (such as the XO-1.75 touchscreen prototypes, and possibly other computers).

Can't reproduce with os11. Please reopen if needed
