zenity_list: can't handle ( nor =

[Hielos]

Hello. I searched for "zenity_list" in the bugs' forum, but I didn't find anything. I am not looking for a solution. I just want to say that there is a bug in 'zenity_list':

octave> zmsg = "Hello";
octave> zcols = {"Choice", " ", "Description"};
octave> zopts = {"TRUE", "FALSE";"1", "2";"f", "df/dx"};
octave> zenity_list(zmsg, zcols, zopts, "checklist", "all");
WORKS

DOESN'T WORK:
octave> zmsg = "Hello";
octave> zcols = {"Choice", " ", "Description"};
octave> zopts = {"TRUE", "FALSE";"1", "2";"f(x)", "df(x)/dx"};
octave> zenity_list(zmsg, zcols, zopts, "checklist", "all");
sh: Syntax error: "(" unexpected
error: zenity_list:
error: called from:
error:   /home/user/octave/zenity-0.5.7/zenity_list.m at line 103, column 5

DOESN'T WORK:
octave> zmsg = "Hello";
octave> zcols = {"Choice", " ", "Description"};
octave> zopts = {"TRUE", "FALSE";"1", "2";"f=k", "df/dx"};
octave> zenity_list(zmsg, zcols, zopts, "checklist", "all");
(This one creates a very odd pop-up list)

I hope this helps

Thanks for bringing this up. For future reference, please file bugs
against packages at the octave-forge mailing list:

The attached patch seems to fix this.

You'll need to explain why this one is odd. It looks quite fine to me,
but perhaps I'm not looking the right places? It could also relate to
the choice of shell as the 'zenity' package just calls the shell. I'm
using bash. Do you use something else?
