[kde-freebsd] 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 net/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.

   I've just posted truss logs for some of the applications at:

- KDE 3 applications
http://people.freebsd.org/~lioux/xorg/kdeinit-truss.log
http://people.freebsd.org/~lioux/xorg/kpersonalizer-truss.log
http://people.freebsd.org/~lioux/xorg/ktorrent-truss.log
http://people.freebsd.org/~lioux/xorg/kwin-truss.log

- Opera
http://people.freebsd.org/~lioux/xorg/opera-truss.log

   Let me know if there is any further information I can provide.

   Backtraces follow.

   Regards,
       Mario Ferreira
