strange behaviour of color property in function graphics [message #89586]

Hi,
I've just came across this:

This is ok:

IDL> i = image(/test)
IDL> t = text(0.5,0.5,'test', 'r', /norm)

This gives an error:
IDL> i = image(/test)
IDL> t = text(0.5,0.5,'test', /norm, color='r')
% TEXT: <LONG Array[1]>.
% Execution halted at: $MAIN$

I think that this is a bug, because:
1) it works for the plot function:
p = plot(/test, color='r')
2) the description of the color property in plot() and text() is the same (set the property to a string or RGB vector: http://www.exelisvis.com/docs/FormattingSymsAndLines.html)

Running the debug option in text, I get the following error:

% ITEXT: <LONG Array[1]>.
% Execution halted at: TEXT 119 C:\Program Files\Exelis\IDL84\lib\graphics\text.pro

Something strange is going on with the color variable being, as the error says, a an array and not a scalar.

cheers,
Helder
