http://xmp.sourceforge.net/ https://sourceforge.net/projects/xmp/files/xmp/3.5.0/ChangeLog/view https://sourceforge.net/projects/xmp/files/xmp/3.4.1/ChangeLog/view If you'd like today's bug-fix update for F-17 to be withdrawn in favour of an upgrade to either 3.4.1 or 3.5.0, just shout, and I'll glady pull them in bodhi.
During final testing of the current test-update, found other oddities (and crashes) in the module probing and fixed several bugs. Else it wouldn't make much sense to publish the test-update. The issues have been reported to xmp devel list. Patch applies cleanly against 3.5.0.
