I recommend a fairly innocuous version bump to 3.4.2. No ebuild changes since 3.4.1.
In the skunkweb-list@lists.sourceforge.net there's a warning on a patch to the layout service. Once it is committed to svn, just let me know :-)
I've checked in the fix for the layout service and released version 3.4.3. Thanks for staying tuned!
