+Subject: [PATCH] scheduler/ipp.c: Allocate device_uri via cupsdSetString()
+
+If a driverless printer has .local in its URI, we resolve the
+URI and save the resolved one as new device URI. The problem was that
+a local pointer was assigned to the structure which is passed to the
+function as parameter, so the pointer became invalid once the execution
+left the create_local_bg_thread() function.
+
+We need to allocate the device URI via cupsdSetString() - the string is
+then freed when the printer is deleted or cupsd shuts down.
+
+Fixes #419.
