Been getting this exact runtime error too. DSLR V4. Curious to find out what causes it. Sparkbooth will freeze and this message box hides behind sparkbooth window so you don't see it until you shut sparkbooth down.
I shoot in program mode with AF turned off and camera's built in flash on.(canon T1 or XSi) Since program mode is quasi auto mode, can I assume that a longer shutter session could be responsible for triggering this error?

It is not recommended to use auto focus, since it can also delay the camera
from taking photos, or cause focus lock errors. If you have to have auto
focus, make sure it is in quick focus mode to decrease the chance of focus
