Sentry Crash Report:

Description Eugene Marcotte 2012-03-25 14:34:41 UTC 
Application: kdevelop (4.3.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.3.0-4.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

Had just folded a function and was adding doxygen comments to it.

- Custom settings of the application:

Running kdevelop inside gnome, not in kde. I've removed a lot of the toolbars and views, mostly just have editor and project pane open.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Eugene Marcotte 2012-03-25 14:38:31 UTC 
The block of code that i was commenting looks like:

	template<class Orientable> 
	void loadOrientation( Orientable o, boost::property_tree::ptree& nodeEntry )
	{
		if( nodeEntry.find("orientation") != nodeEntry.not_found() ) {
			o->setOrientation(
				nodeEntry.get<Ogre::Real>("orientation.x"),
				nodeEntry.get<Ogre::Real>("orientation.y"),
				nodeEntry.get<Ogre::Real>("orientation.z"),
				nodeEntry.get<Ogre::Real>("orientation.w")
			);
		}
	}

I fold it on the opening "{" for the function and then add comments using /** This function {crashs now}

I can provide the full source file if necessary
Comment 2 Milian Wolff 2012-03-29 16:15:44 UTC 
please provide a test case that is reproducible, and/or test in a git master version of kate since it saw some fixes in regard to folding recently
Comment 3 Dominik Haumann 2012-03-29 17:10:44 UTC 
fixed in KDE 4.8.2
