Bug#618835: inkscape: Barcode - Datamatrix dialog gives errors with live preview and bad row/col count
tags 618835 + confirmed forwarded 618835 https://bugs.launchpad.net/inkscape/+bug/738108 thanks Confirmed in inkscape_0.48.1ubuntu2. Looking at the extension script, only a finite set of row/col combinations are valid. It's not a good idea for Inkscape to use spin buttons live preview!
