+This one should be fixed in SVN (r67666)

+The others are "normal" and mostly due to the fact that we can't
+cleanup everything in some library we depend on (e.g. fontconfig).
+BTW valgrind can't help with collected objects as they are
+- correctly freed (by the GC), and
+- correctly detected in System.Drawing (hence the ArgumentException)
+Now the (next) problem is to find which object was collected (looks
+like the brush or the graphic instance from the stack trace) and
+ensure a reference is kept to it.
