[Ironruby-core] possible problem on mono

Could you try to narrow it down to a simple repro? What parameters are passed to “flatten!” that make it fail? (You may want to run it with –D to get full stack information, although it will be slower).

When I try to run the igem script on mono it always comes back with a NullReferenceException.

igem list --debug --backtrace
ERROR:  While executing gem ... (System::NullReferenceException)
    Object reference not set to an instance of an object
    IronRuby.Libraries:0:in `TryFlattenArray'
    :0:in `flatten!'
    mscorlib:0:in `_stub_$2591'
    gem_runner.rb:25:in `run'
    mscorlib:0:in `_stub_$2495'

Is this known or should I add it to the bugs?
