Code Completion crash

[David Nolden]

What the function does is putting overloaded functions of the same name(but 
maybe from different locations) together.

This probably has something to do with the caching, because it only happens 
when you click setCaption twice within the same function-context.

I've workarounded the crash for now, but I'll look at it in detail once I have 
some more time.

greetings, David
