Duplicate of Bug #738108 “Inkscape UI can pass invalid values to Datamatrix extension”?

[Alex Valavanis (valavanisalex)]

Yes, this is almost certainly a duplicate. The bug is fixed in Ubuntu Oneiric, and will also be fixed upstream in inkscape 0.49. Might be worth backporting the patch to Ubuntu Natty and Maverick.
