+1. Shared library breakages are a royal pain in the neck. We should try to get them right earlier rather than later. I'd say file a high-priority bug in the bugtracker, if it hasn't already been. Basically, the library needs to have a different soname EVERYTIME its ABI changes (not just API, mind you). Anything other than that will lead to pain and angry users.
