[Rubycocoa-talk] NSOutlineView crash

[Hans-Georg <pan...@ma...>]

RubyCocoa crashes if I a cell in a NSOutlineView is edited. To verify  
this download the following file from rubycocoa.com:

http://rubycocoa.com/files/outline-views/OutlineMeRuby.zip

Run the project, double-click "Root"  In the NSOutlineView and edit  
the cell content. If you then click outside the cell, the app will  
crash.
