Comment 3 for bug 1310518

This bug can be reproduced using evemu-tools.

I recorded an event sequence which can introduced the bug (but not all the time):

$ sudo apt-get install evemu-tools

$ sudo evemu-device s.prop

this will create a new device /dev/input/event# (# is the number showed in the terminal)

$ sudo evemu-play /dev/input/event# < s.event

Expect behavior: nothing happens.

Actually behavior: Touchscreen/Trackpad/Mouse cursor works fine, but it can no longer clicks.
press keyboard Alt+Tab can make click work again.
