Comment 6 for bug 574157

The following lesstif bug sounds somewhat similar to this bug: https://sourceforge.net/tracker/?func=detail&aid=2912821&group_id=8596&atid=108596, although unfortunately, there's no traction or useful information there w.r.t. what the root-cause is.

The lesstif bug points at Red Hat bug https://bugzilla.redhat.com/show_bug.cgi?id=543647. That bug was apparently solved by a new X server RPM. I *think* the patch is attached to bug http://bugs.freedesktop.org/show_bug.cgi?id=25400 as 0001-dix-if-owner-events-is-true-for-passive-grabs-add-th.patch (that fd.o bug does mention an unspecific ddd issue).
