Hello,
please excuse me if this is not the right place for bug reports, but I haven't
find anything else relevant on the website, like a bugzilla. The search
feature didn't bring relevant results, too.

So, there is a crash bug that happens if you try to copy a "weird" url
(altough perfectly valid) like the one just below:
<http://wiki.modruby.net/en/?c=index>

Version 3.40-2-nossl, on Linux Mandriva 2008.1.
