Package: librdf-ruby
Version: 1.0.10.1-3
Severity: normal
When I run the attached script with line 47 commented out, the script
works as expected. When I uncomment line 47, I get:
/usr/lib/ruby/1.8/rdf/redland/stream.rb:25: [BUG] Segmentation fault
ruby 1.8.7 (2010-08-16 patchlevel 302) [x86_64-linux]
zsh: abort ./restaurants
Simply running the script from the command line and then hitting Ctrl-D
at ruby's CGI prompt exhibits the problem.
Please note that the script uses data from my website, so in order to
see the problem, you may need to be connected to the Internet or copy
the file locally and then run it.
If you need more information, please don't hesitate to ask.
