I cannot reproduce this at all, but I think it might have something to do with the "fallback IMEngine". It does have the "factory", but it is not registered in scim-backend as it is not a loadable module but a part of scim core library. I think scim-backend cannot find the "factory" for the fallback IMEngine then returns NULL. Now I've made some fixes on the CVS to handle such a situation. You can get it from: http://sourceforge.net/cvs/?group_id=108454 I hope this work for you.
Scim-bridge-0.2.5 has been released. This release also contains this bug fixes. (Although I haven't confirmed if it's really okay)
