            Bug ID: 209976
           Summary: ASSERTION FAILED: objectStoreInfo in
                    SQLiteIDBBackingStore::getRecord
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: sihui_liu at apple.com

Normally this assertion will not be hit, but we see cases where objectStoreInfo is null as in the radar. 
So I tried to modify the code a bit by returning error at specific places, and successfully got the assertion failure. Therefore, theoretically it's possible that SQLiteIDBBackingStore does not have requested ObjectStoreInfo in SQLiteIDBBackingStore::getRecord. Then we need to change this assertion to an error and make early return.
