XBMC 12.3, Tvheadend PVR addon, unable to open live transcode settings menu

Can't access Tvheadend "Client specific settings" to enable on-the-fly transcoding on XBMC 12.3 Frodo? 

If you have debug logging enabled following error message will appear on logfile.

ERROR: Window_New: xbmc.pvrclient/Tvheadend HTSP Client - XML File '' for Window is missing, contact Developer 'Lars Op den Kamp, Team XBMC' of this AddOn

This is due wrong path buried somewhere in source. Quick fix is to symlink wrong path to correct path. With Aeon Nox menu is corrupted, but you can still change settings. Using Confluence it works fine with fix below.
