+Summary: UnauthorizedAccessExceptions when browsing file system
+
+Found this from a testcase mailed to the list.
+
+Compile and run Cleanup.exe, click the "..." button to get the file dialog.
+ Browse to a parent directory that contains an unreadable dir.  For me it's
+just a matter of Desktop -> My Computer -> HDD (ext3, sda7)
+
+that HDD is my /home partition.  Anyway, it throws the exception because
+lost+found is not readable to me:
+
+Unhandled Exception: System.UnauthorizedAccessException: Access to the path
+"/home/lost+found" is denied.
