Scale (outside) / Crop (center - center) gives bad result

I have the same problems with crop action in 1.6 and 2.1

Same problem here when upgrading from 1.5 to 1.6, scale+crop does not function correct anymore.
Reverting back to 1.5 solved the problem.

I can confirm this

I get the following errors in my messages:

# warning: Division by zero in [..]/sites/all/modules/imagecache/imagecache.module on line 183.

# warning: filesize() [function.filesize]: stat failed for imagecache/thumb/files/pictures/picture-148.jpg in [..]/sites/all/modules/imagecache/imagecache.module on line 209.

And the following messages in the watchdog:

The behaviour for the keyword "left" instead of "center" gives no problems.

Got the same problem, see attatched screenshot.

same here

Same problem here - as a result all my user's profile pictures are messed up! (I use imagecache profile picture module)
you can see an example here

I'd appreciate any ideas on how to tackle this.
I presume I could go back to ImageCache 5.x-1.3 which seemed to work fine. A quick question - when disabling imagecache module for upgrade (or downgrade) do imagecache presets remain intact in the database. I ask this because a previous upgrade seemed to have messed up my presets.

hansrossel - when you went back to 1.5 did you first disable the imagecache module, updated the new files, reenabled it and ran update.php? What happened to the presets?

This is a duplicate of #242932: revision 1.19.2.36 throws divide-by-zero and other errors when first generating a derivative, which has fixed and committed to dev.

So either use 5.x-1.x-dev, or use the patch mentioned in the above issue.
