Has anything seen this too? Quite annoying... Yes, I've seen it a couple of times. No clue though why it happens, or when. This is not the first time I hit it. This time I analyzed a bit why it was failing and it's because I removed a method manually...I mean, I did MyClass removeSelector: #myMethod And the omEntry is a EpMethodRemoval which represents the exact method I deleted... Also I can see the MultiByteFileStream internal 'collection' is full of none ascii things. I can share a fuelout as well as the image with the files if you want. I can also share the ombu file in question.
