Setting the period to 0 in the Linear Waves distortion filter might crash GIMP

GIMP version: 2.10.14

Operating System: macOS Sierra (version 10.12.6)

Package: Installer from gimp.org

Description of the bug

Inside the Waves (linear waves) Filter: If you set the “Period” slider to zero, GIMP crashes, especially if you do this multiple times, but only if Preview is turned on.

Reproduction

Reproducible?: It’s a little random how quickly the crash occurs, but it is reproducible.

Reproduction steps:

  1. Open an image
  2. Go to Filters > Distortion and select Waves (the first entry).
  3. Turn Preview on if it’s not already.
  4. Set Wave type to Sawtooth.
  5. Drag the Period slider left (to zero) and right repeatedly until GIMP freezes/crashes.

@ Step 2: I’m talking about the linear waves filter. Please test whether the bug occurs with the radial waves filter too. @ Step 4: Please test whether this bug occurs with other wave types too

Expected result: The image preview shows no effect being applied

Actual result: The image preview shows no effect being applied, but sometimes GIMP freezes while trying to update the preview …
