Don't use os.execute, it blocks and the environment isn't set up
properly. Use 'exec' provided by Ion.

You shouldn't call the function here, simply provide a reference to it.
kpress(SECOND_MOD.."F10", mpc_status_osd),

Lua gives this error when it can't find the symbol within local variables
or the globals table.
Are you using Lua 5.0.2? 5.0 used to have a bug that caused functions to
go missing at times.

mpc_status_osd()

If you use os.execute (unrecommended as it blocks), the mpc program
should have finished once it returns. Otherwise, a kludge could be
written using popen_bgread, as the handler given to this gets called
with a nil parameter when the pipe has been closed.
