SWT Exception with Neon Linux GTK3 dark theme setting [message #1752688]

I have an RCP application and the Linux GTK3 version previously built on Mars ran with a Dark theme.

I have now moved to Neon and rebuilt with
org.eclipse.swt.gtk.linux.x86_64_3.105.2.v20161122-0613.jar
org.eclipse.e4.ui.css.swt_0.12.100.v20160517-1505.jar
org.eclipse.swt_3.105.2.v20161122-0613.jar
org.eclipse.e4.ui.css.swt.theme_0.10.100.v20160523-0836.jar

When the user selects the option to set the theme to Dark, which results in a call to the IThemeEngine setTheme method with an argument being the extension with stylesheet URI set to one of the standard style sheets:
platform:/plugin/org.eclipse.ui.themes/css/e4-dark.css

the result is a "Graphic is disposed" SWT Exception (see below).

The same happens when it tries the standard e4_default_gtk.css style sheet.

Some other standard style sheets work.

Is there something wrong with what I am doing?

I should have added that the Windows 10 version of my RCP application works for all the style sheets. It is built with:

org.eclipse.swt.win32.win32.x86_64_3.105.2.v20161122-0613.jar
