Details:

Code to reproduce:


close all
x = 0:0.1:10;
plotyy (x, sin (x), x, cos (x))
legend ("sin(x)" , "cos{x)") 
TeX parse error: syntax error
TeX parse error: syntax error
TeX parse error: syntax error
legend ("sin(x)" , "cos(x)") 
error: set: unknown axes property __legend_handle__
error: called from
    legend at line 198 column 7


The first call to legend had a typo--a '{' instead of a '('--which caused the
TeX parser to throw an error.  The legend, however, was correctly created. 
When I went to correct the text by calling legend again I got an error which I
don't think is correct.
