Summary: KDevelop crashes on load of a source file
[SourceFormatterPlugin::activeDocumentChanged,

QMetaObject::metacall]
Product: kdevelop
Version: unspecified
Platform: Compiled Sources
OS/Version: Linux
Status: NEW
Severity: crash
Priority: NOR
Component: general
AssignedTo: kdevelop-bugs@kdevelop.org
ReportedBy: shaun.reich@kdemail.net
Application: kdevelop (3.9.97 (using KDevPlatform 0.9.97))
KDE Platform Version: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2)) (Compiled from
sources)
Qt Version: 4.6.0
Operating System: Linux 2.6.31-ARCH i686
Distribution (Platform): Archlinux Packages
-- Information about the crash:
Greetings..
I have cleaned all of the settings I could find, the .kdev4 files, KDevelop
starts up properly, but when I try to load a source file (any of many), it
crashes. I didn't load any projects or anything. I was getting the same crash
(I think) before I had cleaned out the settings, except it was *right* when it
started and tried to automatically load the files. It seems like it happened
quite recently, as it was stable a few days ago. Looks like yesterday's trunk
*may* have broken it? Don't quote me on it though.
The crash can be reproduced every time.
