[MusicXML import] reversed wedge not imported
Attached file crashes MuseScore 1.2 (won't fix !) and imports into the current trunk without the hairpin. The file contains a wedge with begin and end reversed (first "wedge type=stop", then "wedge type=crescendo"). This is legal MusicXML and imported correctly by some competitors.
