I confirm, but only on field [code_two]!
Columns with values equal at 0 not seem be affects!

this is what I get in the backtrace stack:

#2 Updated by Giovanni Manghi over 12 years ago

  • OS version deleted (11.10)
  • Operating System deleted (Linux)
  • Priority changed from High to 6

I confirm the issue on Linux and also on Windows.

On Windows/master/osgeo4w is even worst, as it is just enough to select "pretty breaks" and QGIS will crash, even before hitting "classify".
