Fixes for that are in synaptics 1.8 and 1.7.6. It was caused by missing SYN_DROPPED handling.
You'll need libevdev 1.2 or later, iirc to get rid of the bug in synaptics 1.8.
Otherwise, the commit on the 1.7 branch was: http://cgit.freedesktop.org/xorg/driver/xf86-input-synaptics/commit/?h=synaptics-1.7-branch&id=bbaf4d646ebf4393a1ee0eb9bcc569054ed878f9
