kde 3 SIGSEGV inside VNC on XInput_find_display (libXi.so.6)

[Mario Sergio Fujikawa Ferreira]

Hi,

   I am unable to run several applications inside tightvnc. Everything 
worked just fine until the last xorg update.

FreeBSD exxodus.fedaykin.here 8.1-PRERELEASE FreeBSD 8.1-PRERELEASE #4: 
Mon May 31 08:11:18 BRT 2010 
lioux at exxodus:/usr/obj/usr/src/sys/LIOUX  amd64

   All broken applications work under normal X (startx). They just break 
inside tightvnc.

   I am able to start a KDE 4 session inside tightvnc, although most 
apps crash during KDE startup. However, KDE 3 just won't launch. 
Moreover, opera SIGSEGVs under the running KDE 4.

   Ports tree up to date as of yesterday.

   A small list of broken applications:
	1) KDE3
		- kdeinit
		- ksplash
		- kpersonalizer
		- kwin
	2) Opera 10.10

   You may notice a trend of SIGSEGV on XInput_find_display().

   I've just done a full 'portupgrade -af' to make sure everything is 
updated.

   Backtraces follow.

   Regards,
	Mario Ferreira
