Hi,
I have installed jbidwatcher 1.0 and 1.0.1 on my opensuse 10.2 System.
Both versions run fine when I use libX11 in Version xorg-x11-libX11-7.2-15. When the upgrade to the recent version xorg-x11-libX11-7.2-48.1 is done, both version do no longer start.
Error message on console:
java: xcb_xlib.c:52: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.
google leads me with this message to:
http://www.mail-archive.com/ubuntu-bugs@lists.ubuntu.com/msg189472.html
and the explanation for this error can be found here:
http://lists.debian.org/debian-devel-announce/2006/11/msg00010.html
According to this, this is an application error; not a libX11 error.
