Error in <RootX11ErrorHandler>: BadAccess

Hi ROOTers,  

We have recently upgraded from ROOT version 4.04/02 to 5.06/00 at two different sites and encounter the following reproducible error. When trying to close a canvas with the little x button in the corner of the window, the following error message occurs:  

Error in <RootX11ErrorHandler>: BadAccess (attempt to access private resource denied) (XID: 8388608, XREQ: 88)

If another X window, e. g. a TBrowser, is open at the time the whole root session freezes and has to be killed. Looking through the RootTalk archives we found the suggestion to set

X11.FindBestVisual: no

This did not resolve the problem. It is also not an ssh X11 forwarding problem, because it happens when running locally as well.

We are running Scientific Linux, kernel 2.4.21-32.0.1.Elsmp.

Has anyone seen a similar problem?
