This started happening to me today. ** As a workaround, I can open kdevelop with sudo **
so I guess the problem has something to do with sessions. stdout: kdevelop WARNING: deleting stale lockfile /home/bruno/.kdevduchain/{5bb877a5-d8b2-4cdc-b694-6c9b8bf67781}/1/lock kdevelop(10968)/kdevplatform (language) KDevelop::ItemRepositoryRegistry::open: version-hint not found, seems to be an old version kdevelop(10968)/kdevplatform (language) KDevelop::ItemRepositoryRegistry::open: "The data-repository at /home/bruno/.kdevduchain/{5bb877a5-d8b2-4cdc-b694-6c9b8bf67781}/1 has to be cleared." void DBusMenuExporterPrivate::addAction(QAction*, int): Already tracking action "F&ull Screen Mode" under id 85 kdevelop(10968)/kdecore (KLibrary) findLibraryInternal: plugins should not have a 'lib' prefix: "libkonsolepart.so" qrc:/main.qml:23:1: QML QDeclarativeRectangle_QML_0: Binding loop detected for property "areaName" static bool QDeclarativeMetaType::isModule(const QByteArray&, int, int) Qt 4.7 import detected; please note that Qt 4.7 is directly reusable as QtQuick 1.x with no code changes.

This probably reflects a bug in the program. The error was 'BadWindow (invalid Window parameter)'. (Details: serial 2811 error_code 3 request_code 20 minor_code 0) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) kdevelop(10968)/konsole Konsole::SessionManager::~SessionManager: Konsole SessionManager destroyed with sessions still alive pp_macro::definition There were items left on destruction: 236 register count: 0, destroy count 0: kdevelop -version Qt: 4.8.4 KDE Development Platform: 4.10.4 KDevelop: 4.4.1 Running on ubuntu 13.04 Tried the following and none solved the issue kdevelop -n testsession kdevelop --geometry 200x200+0+0 kdevelop --graphicssystem raster kdevelop --graphicssystem opengl kdevelop --geometry 900x900+0+0 kdevelop --geometry 900x900+0+0 --graphicssystem raster kdevelop --geometry 900x900+0+0 --graphicssystem opengl mv ~/.kde/share/apps/kdevelop/ ~/.kde/share/apps/kdevelop.bak -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdevelop in Ubuntu. https://bugs.launchpad.net/bugs/1178843 Title: kdevelop won't start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kdevelop/+bug/1178843/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
