Hi Anton,

It crashes here, you probably need to skip string test if get_URL() 
fails or initialize output variable to NULL so that lstrcmpW can deal 
with it:

../../../tools/runtest -q -P wine -T ../../.. -M wmp.dll -p 
wmp_test.exe.so oleobj && touch oleobj.ok
(0x1520c0)->({94d55e95-3fac-11d3-b155-00c04f79faa6} 0x32f988)
