-- Information about the crash:
- What I was doing when the application crashed:
I was trying to create a try block in the standard hello world code. Hitting an enter after the keyword try and KDevelop crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
