Build Identifier: 20100218-1602

In Red Hat Enterprise 5.3 in a custom RCP application an IllegalArgumentException is thrown after opening a FileDialog, then opening a FormEditor with several pages that contain Section controls with SWT.TWISTIE style, switching tabs in the editor then switching back, then trying to open a Section.  Resizing the window at this point will also throw the exception.

Attached is a project that reproduces the bug.  Also attached is a stack track for the exception.

I've tested this in Windows, and multiple versions of linux including Ubuntu and  Fedora.  The code runs fine in all of those.  I suspect its related to gtk2.10 in Red Hat Enterprise 5.3.

Reproducible: Always

Steps to Reproduce:
1.Create an RCP project that lets you follow the following steps
2.Open a FileDialog, then close it
3.Open a FormEditor with more than one FormPage that contain Section controls with SWT.TWISTIE style.
4.Switch tabs, then back.
5.Try and resize the window or open one of the Sections.

Do you know why the first exception happens (the one in the FileDialog)?

No exception is thrown in the FileDialog.  But you need to open the FileDialog to eventually cause the exception.  I posted the stack trace for the exception, hopefully it makes the situation a little more clear.

GTK2.10 is ancient and no longer supported.
