Description Michael 2004-09-27 09:42:20 UTC 
It looks like under certain conditions a user error handler routine set by 
XSetErrorHandler can be effectively canceled from inside of Xt/Selection.c.

The place to suspect is the loop in the SelectionRequest case of 
HandleSelectionEvents function. Under certain conditions there can be several 
two calls to EndProtectedSection after single StartProtectedSection. Since 
EndProtectedSection zeroes the global oldErrorHandler variable, the second 
call to EndProtectedSection restores the default error procedure instead of 
user's one.

Probably there exist more than one problematic code fragments.
(Checked in 6.6 and 6.8.1 sources).
