Praise the lord - I fixed it.
Just for the record: In three of the hundreds of feeds the
importer_type and/or importer_config field was empty/NULL/0 in the
tx_yafi_importer table. I manually completed the data and now
everything is back to normal. The very question now is why these
fields were empty since they used to be in there for a few weeks.
Let's just assume I made a mistake and didn't notice it.
Amen
