Hi, I’m using Mini Magick and that attachment\_fu plugin to resize images that the user uploads. Everything looks okay in my code, but I get a core dump every time an image is uploaded. The file successfully posts to the application, I can see that the original file gets copied into the folder correctly. It appears that it dumps immediately after that. I’m using Mongrel behind Apache 2 and there aren’t any interesting error messages in the log files. Has anyone seen anything like this before? I’ve been banging away at it for a while. Thank you, – Miles PS: I am currently using… FreeBSD 6.1 Apache 2.2.4 MySQL 5.0.41 ImageMagick 6.2.9 Ruby 1.8.6 Rails 1.2.3 Mongrel 1.0.1 Mongrel\_Cluster 0.2.1 Mini\_Magick 1.2.0 ---

I ran the rake on the mini\_magick gem and it looks really unhapppy… I’m starting to think this might be an ImageMagick installation problem.

I reinstalled ImageMagick and mini\_magick looks a little happier. When I run the tests, this is what I get: (in /usr/local/lib/ruby/gems/1.8/gems/mini\_magick-1.2.0) /usr/local/bin/ruby18 -Ilib:lib “/usr/local/lib/ruby/gems/1.8/gems/ rake-0.7.3/lib/rake/rake\_test\_loader.rb” “test/mini\_magick\_test.rb” Loaded suite /usr/local/lib/ruby/gems/1.8/gems/rake-0.7.3/lib/rake/ rake\_test\_loader Started …mogrify: unable to open module file `/usr/local/lib/ImageMagick/ modules-Q16/coders/2.la': No such file or directory. .....mogrify: unable to open module file`/usr/local/lib/ImageMagick/ modules-Q16/coders/3.la’: No such file or directory. .mogrify: unable to open module file `/usr/local/lib/ImageMagick/ modules-Q16/coders/4.la': No such file or directory. ..identify: no decode delegate for this image format`/usr/local/lib/ ruby/gems/1.8/gems/mini\_magick-1.2.0/test/not\_an\_image.php’. … Finished in 9.735413 seconds. 14 tests, 20 assertions, 0 failures, 0 errors No failures or errors is a good thing, but I don’t know about those results. Maybe that’s how it’s supposed to look, but I’m suspicious. Anyway, I’m turning my attention to attachment\_fu next. – Miles ---

I gave up on attachment\_fu and wrote my own code to do generate the thumbnails (I used Mini Magick). It’s working great, this definitely must have been some kind of problem with attachment\_fu. – Miles
