Incorrect Collisions with mk3 Cargo Ramp
Parts will often break due to a collision when passing through the open space of the part, despite other parts passing through without collisions.
Some examples posted to Imgur:
A stock rover:
The Science Jr. part colliding with the cargo ramp
Redocking the rover, with the science Jr. now gone:
A stock rover, with retracted "Gigantor" solar panels:
they break off when the "gigantor" intersects the plane of the rear of the cargobay:
Note: after repeating this multiple times, it is always the one on the left side (from the point of view of this image).
another example, this time breaking off when loading instead of unloading a rover:
Note that it is again only 1 panel on the same side.
Passing through slowly enough avoids these effects

Confirming that constructions similar to those in the original-report's images, in version 1.5.1 still have retracted panels break when the seem they should be clear of the cargo bay walls. See related bug #18017 for example craft. The speeds required for breakage do seem to be higher, now about 5m/s, double what they were in 1.4.3.
The damage seems to occur at the transition between the MK3 cargo ramp and the hollow MK3 it is connected to, and always on the starboard side of the ramp (the side on starboard of an aircraft using this ramp as its tail).
A different example with maybe the same cause is described at https://forum.kerbalspaceprogram.com/index.php?/topic/177220-tips-for-making-stock-electricjet-powered-propellers-for-vtol-aircraft/
A helicopter craft also showed only the starboard-side elevons breaking, and being F3 reported as colliding with the MK3 ramp below.
