What you're seeing is a combination of Qt's internal image opening
code and MythTV's theme 'fallback' pathway for shared images.
If Qt can't open the requested file, it tries different variations of
the extension to try and locate it (we could tighten this up be only
allowing png files but I honestly don't know if that is feasible).
MythTV wise, if an image file can't be found, the code will then look
in the default theme directories. So for mythcenter-wide it would
check themes/mythcenter-wide, then /themes/default-wide and then
All that said, it does look as if something is broken in your case as
I can't think why it would be looking in for 'title/title_tv.png'.
Perhaps a broken installation as Robert suggested.
