Bug#421854: Not a bug in libx11 or libxcb



tags 421854 + moreinfo
# reassign 421854 opera, except that doesn't exist in Debian
thanks

Hello,

Despite previous comments forwarded to this bug report from
Eirik Byrkjeflot Anonsen, this bug does not lie in libx11 or libxcb.

The reported assertion means that some caller of libx11 has broken locking;
specifically, it calls UnlockDisplay without calling LockDisplay.  (Note that
the functions XLockDisplay and XUnlockDisplay nest, but LockDisplay and
UnlockDisplay do not.)

If opera does not call libx11 directly, the bug likely lies in a library
between opera and libx11, such as a toolkit or an X extension library.

Please try to reproduce this problem under gdb, and get a backtrace.  This
will help us track down where the broken locking exists.  In the meantime,
since no opera package exists in Debian to reassign to, I'll leave this bug
open on libx11 for lack of somewhere better to track it.

Please see
<http://lists.debian.org/debian-devel-announce/2006/11/msg00010.html> for more
information.
