Uploading SVG in picture library fails at thumbnail generation

[robinboening]

Steps to reproduce

Upload a SVG file in the picture library.

Expected behavior

The upload should succeed.

Actual behavior

The progress bar indicates that it failed (turns red). Looking at the logs I can see the thumbnail generation fails during signature creation. Following error is thrown and the new database record for Alchemy::Picture is rolled back. The original svg got uploaded (in my case to S3) though.

NoMethodError undefined method `steps' for #<#<Class:0x00007fa7251f8668>:0x00007fa725731468> in /Users/robin/projects/public/alchemy_cms/app/models/alchemy/picture_thumb/signature.rb:12:in `call'
