+Subject: [PATCH 18/24] Bug 683700 - vdx full of errors
+
+Ensure message_error strings are linefeed-terminated.
+Plus fixes merged from master:
+
+cairo: don't screw cairo's matrix by scaling with 0
+Seen with the VDX attached to bug 683700 - maybe there is also something wrong with the import?
+
+vdx: UTF-8 safe variant to remove last newline
+With the VDX attached to bug 683700 scrambled text appeared. Now corrected with the UTF-8 safe variant to search and replace "\n".
