Bug 130751

Description Sonia Dimitrov 2006-03-07 11:40:56 EST

With build I20060307-0920, I am unable to close any editors without an error dialog opening with the message "Error notifying a preference change listener.  Check the log for details".

I can also reproduce on a fresh install and workspace by creating a new project, then a new build.xml file.

The .log contains the following:

!ENTRY org.eclipse.ui.workbench 4 2 2006-03-07 11:30:00.484
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".
