Re: Crashes with a webview. (Rubycocoa-devel 1080) - RubyCocoa

Well I don't know why I missed it but the code that leads to the crash
is a notification callback from the webview. I still don't know yet if
all my problems are over and why that notification sometimes works and
sometimes not, but if it does continue I will try to put something
together.

Thanks Laurent and sorry for the clutter in your inbox :)
