Comment 12 for bug 518122

Due to every advantage I would get, I did the do-release-upgrade in my production server from 9.10 to 10.04 ... of course, redmine was dead due to this issue.

I had then download the packages Marco has built and presto - redmine is a O.K. now. I am not 100% sure if this fix breaks something else or even if it is built 100% according to Ubuntu recommendations but it was good enough for me. I do not recommend everyone to try this before it gets a better checked unless you really know what you are getting into. Be aware!

His zip (follow the comment #8) comes with three .deb files and a quick sudo dpkg -i *.deb gets them going. If anything else seems to malfunction, sudo apt-get autoremove --purge librmagick-ruby1.8 librmagick-ruby librmagick-ruby-doc will clear them up, and a sudo apt-get update && sudo apt-get install librmagick-ruby will get the official (crippled) back on your system.

If you are like me, --stupid-- I mean, brave enough to try this out, whether it works or not you your system, please, report back here so the developers can learn what is going on, and most likely, put a equivalent fix in the repository (at least as a candidate, who knows, at the back-ports) ASAP
