GTK+-Direct FB crash when an SWT Image is created

[Rene Engbers <rene engbers philips com>]

Hello,

On an emmbedded device we have a Java-SWT
application. I have a very small Java-SWT application that just shows a
hello world button and cretates an object of the (SWT) class Image. At
the moment the object of the class Image is created, Direct fb terminates
with a 'signal 11' (if we 'comment out' the creation of the image, the
crash does not occur):

(gdb) print draw_impl->surface
$2 = (IDirectFBSurface *) 0x0

The surface attribute is null and results
in a crash.

We use the Java CDC foundation profile
virtual machine (version 1.0.1), SWT (version 3.064), GTK+ for Direct FB(version
2.0.9-2) and Direct FB(version 0.9.22). All examples from GTK+ run fine,
so various widgets and images are shown on the frame buffer (the pixmap
example also works fine).

Any suggestions would be welcome! Thanks,
Rene
