The callback for the fontsize property on legends has to re-create the legend object entirely. This means the existing graphic objects get destroyed.

I pushed more of a complete hack here (http://hg.savannah.gnu.org/hgweb/octave/rev/132d9f543cc5).

I tried to debug this and surrounded print.m:409:

and run the script

Why is the handle for the legend text no longer a handle after a call to set?

still fails with default 5b0036d89d4a (after e477578fca3d), fltk and gnuplot backend.

The bug is not fixed for me. It's just fixed for the first try, but for the second plot it still occurs.

Fixed in this changeset (http://hg.savannah.gnu.org/hgweb/octave/rev/e477578fca3d). This will be a part of the 3.8 release due out in a few weeks.

title, xlabel, ylabel and text are working fine, only using legend triggers this bug.

Both, gnuplot and fltk toolkit are affected.
