I get the below error with my project Kontur, in revision 3dfbc634f6b25e2389114da929fe7f3f2c8b5970 as downloadable from

http://github.com/Sciss/Kontur/tree/3dfbc634f6b25e2389114da929fe7f3f2c8b5970

i have attached the contents of the library folder, so in order to reproduce the crash, you can copy them there and run ./compile.sh (set $$SCALA_HOME before)
