Version: 3.0.2 (using KDE KDE 3.2.1) Installed from: Slackware Packages Compiler: gcc 3.3.3 OS: Linux KDevelop crashes when opening a project or trying to create a new project. I have disabled ALL plugins and it still crashes. I have tried changing the editor to the qt editor and it still crashes. I am using Slackware-current: Qt 3.3.1, KDE 3.2.1, KDevelop 3.0.2 I recompiled kdevelop from source using --enable-debug=full flag and ran gdb on it, and below is as far as I got -> it crashes after the cpp BackgroundParser QThread is started. kdevelop (core): dcop emitting project opened Breakpoint 3, MainWindow::slotReactToProjectOpened() (this=0x81489f8) at mainwindow.cpp:1250 1250 for (; it.current(); ++it) { (gdb) break mainwindow.moc:187 Breakpoint 4 at 0x806aeb7: file mainwindow.moc, line 187.

Never mind, after learning a bit more about using gdb with a threaded program, I figured out that the crash was because of a seg fault in the KDE Style I was using: Program received signal SIGSEGV, Segmentation fault. 0x42042d44 in slickerstyle::drawComplexControl(QStyle::ComplexControl, QPainter*, QWidget const*, QRect const&, QColorGroup const&, unsigned, unsigned, unsigned, QStyleOption const&) const () from /opt/kde/lib/kde3/plugins/styles/slicker.so
