Bug 323341

Application: kdevelop (4.5.60)
KDE Platform Version: 4.11.60 (Compiled from sources)
Qt Version: 4.8.5
Operating System: Linux 3.10.5-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
When KDevelop is scanning your project, and the root element hasn't yet been added to the project browser, performing any action that needs to access it crashes the program.

This particular backtrace is from clicking the "locate current document" button, but this crash has happened to me in other situations.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
