I'm using Ubuntu 9.10, Linux 2.6.31-17-generic and GNOME 2.28.1 What steps will reproduce the problem? 1. Install eclipse for RCP (eclipse-rcp-galileo-SR1-linux-gtk.tar.gz) from eclipse.org 2. Open Preferences dialog 3. Either press the Ok or Cancel button, when the dialog closes, two errors appear in the Error Log view: "org.eclipse.swt.SWTException: Widget is disposed" and "Problems occurred when invoking code from plug-in: org.eclipse.jface" -- Error Details -- Date: Sun Jan 24 23:32:44 PET 2010 Message: org.eclipse.swt.SWTException: Widget is disposed Severity: Error Product: Eclipse 1.2.1.20090812-1036 (org.eclipse.epp.package.rcp.product) Plugin: org.eclipse.jface Session Data: eclipse.buildId=M20090917-0800 java.version=1.6.0_16 java.vendor=Sun Microsystems Inc.

I assume you have a screen reader running? If so, you should be able to work around this by turning it off. Accessibility has undergone major changes in the 3.6 stream, so it's possible that this may now be fixed as a side effect. Car or SSQ to confirm.
I believe this is fixed in HEAD and 3.5.2 (See bug#291128). Please try the latest maintenance build.
Please reopen if not fixed in 3.5.2. *** This bug has been marked as a duplicate of bug 291128 ***
