panic on INSERT ... RETURNING ScalarFunc(empty blob)

Schema:

CREATE TABLE "testtable" ("data" BLOB NOT NULL);

Query:

db.Query(`INSERT INTO "main"."testtable" ("data") VALUES (?) RETURNING SCALAR_FUNC("data");`, []byte{})

When the data column is empty (passing []byte{}), sqlite panics during query execution, before calling SCALAR_FUNC(). If it is not empty, everything is fine
