Failure: Could not find membership record: - when saving an existing contribution if there are no membership records in the database

Fatal error when saving an existing contribution record - only occurs if civicrm_membership table is empty. The code in CRM_Contribute_BAO_Contribution::transitionComponents (lines 1388-1405) is "mistakenly" looking for an associated membership record. I think part of the problem is that the 'membership' item in $componentDetails is an empty array in this case (due to price sets change). This would have been a null value previously.

$ids['membership'] = CRM_Utils_Array::value( 'membership', $componentDetails );

To recreate - delete all membership records. Then edit any existing contribution record - you'll get the fatal error. You can make the error go away by creating a membership record FOR ANY CONTACT (does not need to belong to the contact whose contribution record you've been editing). This indicates that the code which is "looking for" a related membership record is NOT doing the right thing at all.

1. Should not be trying to transition a membership record when there isn't one linked to THIS contribution.
2. Should not fix the problem simply because some random membership record exists in the DB
