Subject: 28.1.50; Calling "convert" from thumbs.el is broken
Date: Mon, 04 Jul 2022 01:48:56 +0200

* dired to a directory with images that are larger than 100x100 pixels

* M-x thumbs-dired-show

* I get a buffer with the first few images in the directory in their
  original size

* I expect the images to be scaled to thumbs smaller than 100x100,
  see thumbs-geometry

Tracing the code I stumble onto thumbs-call-convert.  Some time in the
past this was converted from using the shell to passing the parameters
directly, but the fallout was not handled correctly.

I will post a patch as a follow-up.
