[Bug awt/32082] New: mauve TestPaintGraphics causes assertion failure in gnu_awt_peer_gtk-ComponentGraphicsCopy

[timo dot lindfors at iki dot fi]

Steps to reproduce:
1) cacao Harness gnu/testlet/java/awt/Graphics

Expected results:
1) mauve test passes

Actual results:
1) mauve test reports two failures and then cacao throws assertion failure:

FAIL: java.awt.Graphics.TestPaintGraphics
  line 65:  [1] -- boolean passed to check was false
  line 66:  [2] -- boolean passed to check was false
FAIL: java.awt.Graphics.clearRect
  line 45:  [1] -- objects were not equal.  Use -debug for more information.
  line 81:  [14] -- got 40 but expected 200
  line 82:  [15] -- got 40 but expected 200
  line 83:  [16] -- got 40 but expected 200

TEST RESULTS:
2 of 2 tests failed.  6 total calls to harness.check() failed.

** ERROR **: file
../../../../native/jni/gtk-peer/gnu_java_awt_peer_gtk_ComponentGraphicsCopy.c:
line 111 (Java_gnu_java_awt_peer_gtk_ComponentGraphicsCopy_copyPixbuf):
assertion failed: (widget != NULL)
aborting...
cacao: string.c:399: javastring_new_from_utf_string: Assertion `utfstr' failed.

More info:
1) I'm using classpath and mauve cvs heads from 2007-05-24 and cacao 0.97-4
that ships with debian unstable (on x86).
2) The bug does not occur with classpath from 2007-04-25T12:00:00 but it does
occur with classpath from 2007-04-26T03:00:00
3) Diff between these two dates shows the following changelog entry:
