xfwm4 segfault

[Jens Luedicke]

Hi Olivier,

I updated xfce4 from svn and xfwm4 is segfaulting on my laptop (rev 20600):

The revision 20584 I have on my PC works though.

a working fix suggested by Jannis:

<JPohlmann> perldude: Try to replace *protocols = None with protocols = None.
<JPohlmann> In line 133 of hints.c.
