Package: octave-forge
Version: 2004.11.16-6
Severity: normal

The 'legend' command fails the first time it is called and then works
fine after that.  The error message is:

error: invalid row index = 0
error: evaluating argument list element number 1
error: evaluating argument list element number 1
error: evaluating prefix operator `!' near line 190, column 7
error: if: error evaluating conditional expression
error: evaluating if command near line 190, column 3
error: called from `legend' in file `/usr/share/octave/site/m/octave-forge/plot/legend.m'

Attached is a very simple script to illustrate the problem.  Run with
'octave -f legend_test.m'.  ('-f' ignores rcfiles at startup, just to
show that it's not a configuration problem.)
