Opened Kdelive this morning. Opened a project from last night. Saved to anther file. Tried to edit a Title Clip. Comes up with error:
"Please set a default application to open images in the Settings dialog"

First time this error has appeared.

Closed down Kdelive. Reopened it several times. No change. Checked 'settings'. No 'default application' for images showing anywhere.

What's going on here?
