With the curious references to nvidia in the backtrace I removed all nvidia drivers from the system and no further crashes occurred. I reinstalled the desired nvidia driver again and no crashes resulted.

[David Newman (drdrnewman)]

I have recently accepted a KDE and MythBuntu update, and this bug has appeared. Previously I have never had problems with mythfilldatabase.

[paul summers (paulsum)]

this occurred in the past, but using latest nvidia drivers fixed it (i think), but this time I am not using Nvidia drivers... ( just the stock drivers that are included the updated 12.0.3.

i am using a haswell g3420 Intel graphics, with vaapi normal.

this bug is not really important does not really cause problems except for the error popup.

but was DOES cause errors is the front restarting/crashing because you are exiting the video/tvshow you are watching using the esc key...

dont think that this bug has to do with the playing of tv shows...
