[Pkg-octave-devel] Bug#515743: octave3.1: 3.1.51 and 3.1.52

We have already explained this, apparently it is not a bug.

About the title size to be different from before, it is in fact not a
bug.  It was caused by a workaround of mine to the 3.1.51 bug that made
it unable to find the right fonts.  So not a bug here either.

This is apparently a regression.  I just posted a patch to octave-bugs
that solves the problem for me by reverting to pre-3.1.52 behaviour:
