+Subject: [PATCH] Don't muck with per-process global sqlite configuration from
+ the db backend
+
+sqlite3_config() affects all in-process uses of sqlite. librpm being a
+low-level library, it has no business whatsoever making such decisions
+for the applications running on top of it. Besides that, the callback can
+easily end up pointing to an already closed database, causing an
+innocent API user to crash in librpm on an entirely unrelated error on
+some other database. "Oops."
+
+The sqlite API doesn't seem to provide any per-db or non-global context
+for logging errors, thus we can only remove the call and let sqlite output
+errors the way it pleases (print through stderr, presumably).
+
+Thanks to Jan Palus for spotting and reporting!
