calibre-git 2.71.r46.gf8c1dd4 on 32-bit Linux here, and that (default menu) is indeed what I am seeing for some reason, but I have no idea why.
I figured that wasn't deliberate.

Any idea
why that might happen?
Tonight I can try testing it with an earlier version of the plugin... (I actually have a bunch of plugins archived in git because $reasons.)
