MiniMagick... Core Dump when Reszing Images?

Rails
1

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:

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.

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.
