Probably not .. I'm quite sure it's the Change Listener.. .
Although, working with different versions is kind of "dangerous". Make sure you always import objects from a lower build to a higher build .. and compile (never forget to compile). Moving objects from an environment with a higher build to one with a lower build is "dangerous" .. mainly when doing that with reports. I have seen systems that crash .. and take a long time to be able to get it running again .. .
