Just wondering, the "/" shortcut ("Find as you type"), is disabled on the menu. But you can call it manually pressing the "/" key

I experienced the same problem under 4.2.2 installed from Debian unstable.
Maybe inline '/' search should just be removed, since ordinary ctrl+f search is also incremental now. The duplicate code is just a source of bugs, and if we tie '/' to ordinary search the functionality is still there.
