Version: 3.9.97 (using Devel) Compiler: gcc 4.4.1 OS: Linux Installed from: Compiled sources This is happening for me with KDE 4.4 Beta 1 and 2, both on Kubuntu Karmic. Most recently on Version 3.9.97 (using KDevPlatform 0.9.97) Using KDE Development Platform 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2)) Reproducible for me by having several projects open, having 'reload projects on startup' checked, and the background parser on with 500ms delay and 1 thread. Happens about 8 out of 10 times, sometimes directly on startup, sometimes after opening another project via the file dialog; it's a bit of a moving target, which makes it seem like a thread synchronization issue to me. I ran KDevelop through gdb and got the following backtrace: Almost in all backtraces related to this crash, there's one of the Qt libs in the call stack. Is there something in Qt not threadsafe that KDevelop is assuming it is? ======= Backtrace: ========= /lib/libc.so.6[0x7ffff546bdd6] /usr/lib/libsqlite3.so.0[0xkdevelop(7689)/kdevelop (cmake support debug) CMakeProjectVisitor::visit: (ni) File append: "#[bin_dir]/CMakeOutput.log" "Compiling the C compiler identification source file "CMakeCCompilerId.c" succeeded.

The backtrace is useless as it is. If Dr. Konqi doesn't show up for some reason when it crashes, please run kdevelop in gdb and issue "thread apply all bt" once it crashed.
I sort of figured there wasn't just a ton of useful information in it - here's a new backtrace after running in gdb and thread apply all bt on crashing. Note that this is not using debug builds but simply the standard packaged in kubuntu. I can run this using the debug versions, or make a local debug build, if necessary, but don't know how reproducible it'll be, seeing how it's a bit transient already.
