Yes, master contains work in progress. If you want stable code, you
should use the release branch.
Note that the "fully cooked" narrowing will not magically solve that
problem, though. Logview will have to be adapted to deal with the
possibility of a locked narrowing. What you should most probably do in
your case is to increase the value of long-line-threshold (or disable
whatever causes Logview to infloop when locked narrowing is in effect, if
that's feasible).
