Occasionally, Anaconda seems to lose it's mind and just continuously register new handlers. Not sure what triggers it, but my ST console looks a bit like this:

I just noticed the bit about "FindKeyConflicts" in the error log, so it might be the combination that makes things go awry. I'll try removing that and see if it helps.
