+Summary: ListView: Stackoverflow in MWF unit tests
+
+The unit tests on my local Ubuntu 7.04 box abort due to a stackoverflow. 
+I've always assumed this was some local issue, but apparently the 
+monobuild MWF tests on redhat-9-i386 also fail. 
+
+I'm not sure if it's the same issue. Can someone, who has access to that 
+box, check out the log file of the MWF test ?
+
+On my local machine that log contains the following errors:
+
+System.NullReferenceException: Object reference not set to an instance of 
+an object

+
+Modifying ListViewItem.Layout to do nothing if owner is null fixed the 
+problem for me.
+
+I haven't been able to reproduce this with a small app.
