The fallback code in remote.c for when DBUS isn't available hasn't been kept
up-to-date with the rest of the code, so if you don't have DBUS installed
xfmedia won't compile (even though it's clearly meant to).

Reproducible: Always
Steps to Reproduce:
1. Remove DBUS.
2. Compile xfmedia.


Actual Results:  
The compilation failed messily.

Expected Results:  
Compiled happily.

Patch to fix it attached.
