Bug 75708

Version:           3.0.1 (using KDE KDE 3.2.0)
Installed from:    Gentoo Packages
Compiler:          gcc (GCC) 3.3.2 20031218 (Gentoo Linux 3.3.2-r5, propolice-3.3-7) 
OS:          Linux

KDevelop crashes when I close one of the tabs in IDEAl mode with the shortcut combination Alt+Ctrl+Shift+L/R/B. However it only happens if I do _not_ open any files from my project first, eg. the IDE is "empty".

I've only tried it with PHP projects, which have a single PHP page opened, which could have something to do with it crashing.

The crash happens with both left / right / bottom tabs. If I open a file and close it again the crash is _not_ reproduceable. The crash only happens when I use the shortcut key, not if I use the mouse to close the tabs. It doesn't matter which of the individual tabs are opened.

I can reproduce this everytime.

To reproduce:
- Start KDevelop and make a new project (PHP in my case)
- Close all opened files
- Close KDevelop
- Restart KDevelop (I assume the project is autoloaded)
- Press Alt+Ctrl+Shift+L twice in a row (KDevelop should then crash)
