It's possible that your theme is trying to define an invalid area for drawing some widget.

What theme are you using?

Please attach the entire "-v gui" log from the mythfrontend session, i.e. start "mythfrontend -v gui", navigate to the problematic Watch Recordings screen, exit mythfrontend, and attach the resulting mythfrontend log file.

Definitely possible that there is an invalid drawing. I am using theme: Mythbuntu-26.15

See attached log from: mythfrontend -v gui

This appears to be a problem with the Mythbuntu theme (despite the lack of clear diagnostics from MythTV), specifically two incorrect elements in recordings-ui.xml: 

<area>0,0,0,0</area>

and 

<area>0,0,0,31</area>

These are specifying zero width and (in the former case) zero height.

Please bring this to the attention of the Mythbuntu theme developers.
