stk: Path to soundfiles not found

[Peter P.]

Hi, 

and thanks for packaging stk.

Starting /usr/bin/stk-demo from the package as
	stk-demo TubeBell -or
throws an error
	FileRead::open: could not open or find file (../../rawwaves/sinewave.raw)!
while the file searched for is in
	/usr/share/stk/rawwaves/sinewave.raw

This is stk 4.5.2+dfsg-4.

If I should file a bug report please let me know how.

Thanks again,
Peter
