That was the sequence I started with on the K-3 and it did not drop out of LV. If the K-5 behavior is different, that may be an explanation if the paint on the Ennalyt is patchy.

The lens is reportedly causing your camera to abruptly drop its mirror and close its shutter.
What I would do is to:- Closely examine the two power pins just inside the camera's mount throat at the bottom of the mirror box
- Check too for evidence of abrasion on the adjacent portions of the mirror box
- With the lens off the camera, evaluate the position of the tangs as they would be during a normal mount
- Measure the depth of the furthest intrusion of the tangs into the mirror box (flange face to rear tang surface). Compare that to the depth of the contact pins in the mount. The pins' tops are not particularly deep (~7mm) and the clearance of my Exakta-mount lenses would be pretty slim.
It is hard to say whether the pins on your camera are energized during live view, but even if they are not, they are not something we want to be pushing around with blunt objects.

I am not sure which contacts pentasonic was referring to, but I am curious as to whether the tangs on the Ennalyt are shorting out the power contacts in the mirror box. Some Ennalyt models have fairly robust versions of the Exakta mount (thick tangs). If they are contacting those pins at all, it is not a good thing, particularly if the pins should get bent. This is even a hazard with the aperture actuator pin on some M42 lenses.

I can't say for the K-5, but my K-3 is quite happy to do live view with a non-conductive mount or with no lens at all attached.

Details, please. Did you adapt to M42 or K-mount? Which Exakta-mount lens?
This is probably not related to the other stuff above. Bracketing uses the exposure compensation feature and may produce strange results depending on exposure mode and the bracket order.
