fractalize make division zero (reproductible case)

[Popolon2]

With today SVN version of Inkscape

Open the attached file :

launch the fractalize script with parameters :
Subdivisions : 6
Smoothness : 4.0

This error log is displayed (ZeroDivisionError) :

[Popolon2 (popolon2)]

Originator: YES

working solution,
replace :
      nx = -y3/length
      ny = x3/length

By
    if length != 0:
      nx = -y3/length
      ny = x3/length
    else:
      nx = 1
      ny = 0

(use attached patch)

File Added: fractalize_divzeo.patch

[Bryce Harrington (bryce)]

If this is still an issue, we should incorporate this patch for 0.46.

[Popolon (popolon)]

I have already fixed and commited in svn, (there was the fixed/commited status) I put it back to this state

[Popolon (popolon)]
