Package: inkscape
Version: 0.48.1-2
Severity: normal
I just tried Extensions > Render > Barcode - Datamatrix
I checked "Live preview" and clicked the spin buttons for "Rows" to
see the images grow.
When i hit Rows == "19", a new dialog box popped up, with this
message:
Inkscape has received additional data from the script executed.
The script did not return an error, but this may indicate the
results will not be as expected.
---------------------
Unrecognised DataMatrix size
Traceback (most recent call last):

nrow, ncol )

--------------
It seems to me that the spin buttons shouldn't allow the user to
choose bad values (e.g. enforce a range), but i don't know enough
about datamatrix to know if that's acceptable or not in a 2-D
constraint. For example, maybe 200x200 is OK, but 200x10 is not. if
that was the case, then starting with 10x10, you'd have no way to get
to 200x200.
So maybe the right fix is for the live preview to simply disable
itself when the dimensions are unacceptable, with an in-window display
of why it's not working.
