UMS working directory is included when setting an arbitrary path in mplayer_path configuration option

What steps will reproduce the problem?
1. set mplayer_path = <mplayer binary> in UMS.conf
2. restart UMS
3. cat debug.log | grep mplayer

What is the expected output? What do you see instead?

Please provide any additional information below.
Using a different mplayer binary, the workaround can be achieved, as follows:
1. remove mplayer_path configuration option from UMS.conf
2. rename (or delete) mplayer binary supplied in $PMS_PATH
3. create a symlink to the desired mplayer binary in $PMS_PATH
