iPhoto 9.5 sharpening drastically affects red channel

I have the weirdest bug: opening a photo into the "edit" window recalculates the edits and ties the "sharpening slider" to the photo's "red channel." There are no visible slider changes, but a beautifully edited photo is suddenly converted to peaked reds. This renders the sharpening slider and the editing panel more than useless – they damage the photo. I don't even have to enter the adjustement pane for the change to occur. Command + E is sufficient to recalculate, bringing my work to a standstill.

Everything since the last update has been working properly, at least until the latest "Digital Camera Raw Compatibility Update 5.01." I use a Sony NEX but only save JPEG and never RAW. The Sony Alpha NEX-5T is included in the update, but I'm shooting with a Sony NEX-5, which is an earlier generation model.

I've also confirmed the "sharpening/red channel" bug is present in Aperture v3.5 – RAW 5.01 – Build 718.1, and RAW Support 5010 – Build 91.8.

Is there a way to revert to the previous RAW build? Is there a patch? Am I just forced to wait on Apple?

Update: I've had to manually restore my photos by sorting through tens of thousands of masters and previews (edited photos). I've recovered more than 20 GB of lost photos, which I'll now have to sort through to remove photos which should have already been permanently deleted. I've found that imports have even failed to show some photos, and the file structure began to breakdown with iPhoto 9.4 and got even worse with 9.5 (tens of thousands of photos placed in individual folders). Aditionally edited photos have even been rewritten as distored images.

If you have more than 30GB in your library (the limit Apple's specialist says she keeps for herself) I suggest you create a new library immediately and/or abandon iPhoto altogether. I'm giving Lightroom 5 a shot and if that fails then Capture One Pro 7. Since Aperture now fuses it's library with and requires iPhoto, I'll never feel comprortable trying to make that switch.

Good Luck.
