解決策を見つけました。トリッキーなものですが、機能します。のパッチを作成しましたpaperclip-3.3.1：
diff -r --unidirectional-new-file paperclip-3.3.1/lib/paperclip/geometry.rb paperclip-3.3.1-my/lib/paperclip/geometry.rb
23c23
< Paperclip.run("identify", "-format %wx%h :file", :file => "#{file_path}[0]")

ペーパークリップは、例外処理なしで、trueまたは-を返すのではなく、単に例外を発生させていたようです。falseそして、これが主な失敗でした。
