Dashcode (3.0.5) crashes in Mountain Lion (10.8.4) I'm trying to get Dashcode to run in order to make a dashboard widget to surprise my friend. The app opens but crashes almost instantly (even in safe mode and Mavericks). The console yields the following errors:

Dashcode interacts with the iPhoto library on startup - Start iPhoto with the option and command buttons held down. You then get an option to rebuild the library (there are four different radio buttons, start at the top - checking whether DashCode launches between each rebuild - if it doesn't work still try the next rebuild option in iPhoto)
