When I try slice the attached file I get a crash with this error: "
Traceback (most recent call last):

and another error:
"
Calling error for procedure 'gimp-image-crop': Procedure 'gimp-image-crop' has been called with value '0' for argument 'new-width' (#2, type GimpInt32). This value is out of range. "
Does anyone know why I am receiving this when I slice the file. The file is too big for attachments so here is the link on dropbox: https://www.dropbox.com/s/0v8kdoickcmgs36/test.xcf?dl=0

It is not the plugin, it is your image and in particular the guides. Many duplicates, see screenshot

Remove all of them, and replace at the 301 x 301 pix spacing. Attached a script for multiple guides, guides-grid.scm and the script listguides.scm

You also have an active selection there, does not affect py-slice.py but not good practice.

This worked perfectly thank you for the help and for the plugins, that'll be a lot easier than using guides by selection while snapping to a grid. I didn't realize that would cause double ups.
