Public bug reported:

HW configuration: MX51 EVK board
SW configuration:
1. Install xserver-xorg-input-evtouch page (version: 0.8.8-0ubuntu6.1)
2. Add fdi file by "vi /usr/share/hal/fdi/policy/20thirdparty/50-mxc-ts.fdi":
<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
  <device>
    <match key="info.product" contains="mxc_ts">
        <merge key="input.x11_driver" type="string">evtouch</merge>
    </match>
  </device>
</deviceinfo>
3. reboot the board, X crash. The backtrace is as follows:
Program received signal SIGSEGV, Segmentation fault.
0x402edae4 in strlen () from /lib/libc.so.6
(gdb) backtrace
#0  0x402edae4 in strlen () from /lib/libc.so.6

    flags=<value optimized out>) at evtouch.c:1167
#4  0x000861c8 in ?? ()
#5  0x000861c8 in ?? ()

However if i down-grade xserver-xorg-input-evtouch to version
0.8.8-0ubuntu3, Touch screen works fine.

So what's the possible difference cause this issue?
