Comment 155 for bug 185311

Please note that the problem is triggered in stable applications which have been running correctly for many years on many platforms including *BSD, Solaris and Linux. The problem is clearly not in the application, but in XCB. One example of a non-fatal fault in Desktop CYBER is below:
