Lionel Elie Mamane 76a74b72db fdo#50372: crash when refresh of last already-known row unexpectedly fails 
Instead, try to do the least unreasonable thing:
Fetch a new row
If that fails because no new row to fetch, at least we are properly positioned after last row. Calling code may not expect that and get confused, but that is the best we can do.
