Title:
  Inkscape UI can pass invalid values to Datamatrix extension

Status in Inkscape: A Vector Drawing Tool:
  Fix Released
Status in inkscape package in Ubuntu:
  Fix Released
Status in inkscape package in Debian:
  Fix Released

Bug description:
  Binary package hint: inkscape

  This bug in Inkscape's handling of the Datamatrix extension was
  reported in Debian: http://bugs.debian.org/cgi-
  bin/bugreport.cgi?bug=618835

  * Go to Extensions->Render->Barcode - Datamatrix
  * Select Rows = 19, Cols = 10,  Square Size / px = 4
  * Click "Apply"
  >> The extension raises an error

  The main problem here is that Inkscape uses spin-buttons in the
  extension dialog, which invite the user to scroll through any
  combination of row/col values.  However, the extension itself only
  accepts a finite set of combinations... in other words, the user can
  very easily select an invalid input for the script.  Combining this
  with "Live preview" leads to bad results!

  It might be better (if a bit ugly) to have a drop-down list containing
  only the valid row/col combinations.
