It still crashes... :( /usr/lib/ruby/gems/1.8/gems/activesupport-1.4.4/lib/active_support/core_ext/module/inclusion.rb:4: [BUG] gc_sweep(): unknown data type 0x0(0xac53841c) ruby 1.8.6 (2008-03-03) [i686-linux] Once, there was a crash message related to gettext, but I've made an upgrade and it crashes like that. How to trace or debug that? m.
