Oh lord! I've had enough of reading that you're working on it, WA. You were made aware of the issue on the 7th of October and it's now the 21st of January. That's more than three months of crashes just trying to use DataBridge, which is a fantastic extension when it works.
If this was a free / open-source product I'd be happy to turn a blind eye, but we've paid our money, we keep it up to date and we're (mostly) happy for paid upgrades when necessary.
It's probably about time you put a clause on DataBridge's main page saying that it might not work on Yosemite.
