2 tests, 3 assertions, 1 failures, 0 errors



Im running Ruby 1.8.1 from the 1-click-installer on WinXP
using RedCloth 2.0.11. The same happenes when running the test using Linux


While it doesn't make too much sense to have this order of '*' and '**',
the given situation is the smallest and closest piece of RedCloth I
could com up with that shows this behaviour.

The original data ia a list with a sublist with one line similar to
"!pic/pic.png!:http://www.rubygarden.org/". In _that_ situation the
result is the same ("undefined method `length' for nil:NilClass"),
except that the problem disappears after inserting a space before the
line containing the link.

May be I'll dig a bit deeper into this tomorrow...

Am I missing something? May be it's time to get me some sleep. ;-)

Happy rubying

Stephan
