Hi,
I was hoping to use Xvnc as a server to host some GTK+ apps, but GTK
apps running on the server error out with the following:
gtk-demo --sync
The program 'gtk-demo' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
(Details: serial 85 error_code 1 request_code 146 minor_code 2)
...
Having dug into this some more, in gdb with a breakpoint on _XError:
#0 _XError (dpy=0x807b780, rep=0xbf86ed50) at ../../src/XlibInt.c:2874

Versions installed (From Ubuntu Fiesty):
vnc4server 4.1.1+xorg1.0.2-0ubuntu4
libgtk2.0-0 2.10.11-0ubuntu3
libxfixes3 1:4.0.3-1
I invoked vnc4server with:
vnc4server :1 -nohttpd -name foobar -depth 24 -geometry 1024x768
Is this a GTK+ bug, a bug in the VNC server, or something I must
workaround?
Regards,
