Version: 4.2.60 (using KDE 4.5.5) OS: Linux I have permanent kdevelop crash with all versions including the latest trunk at the moment when I invoke the 'Find/Replace in Files' dialogue. I run the kdevelop in the ddd session and can see that function void GrepOutputView::replacementTextChanged(QString) from the file plugins/grepview/grepoutputview.cpp is called and crashes. Below is the gdb output: Program received signal SIGSEGV, Segmentation fault. GrepOutputView::replacementTextChanged (this=0x550ba00) at /home/leonp/kdev-trunk/kdevplatform/plugins/grepview/grepoutputview.cpp:127 (gdb) p model() $1 = (GrepOutputModel *) 0x0 (gdb) up #1 0x00007fffec4adbd4 in GrepOutputView::qt_metacall (this=0x550ba00, _c=QMetaObject::InvokeMetaMethod, _id=<value optimized out>, _a=0x7fffffff9fa0) at /home/leonp/kdev-trunk/kdevplatform/build/plugins/grepview/moc_grepoutputview.cpp:112 (gdb) p *_a $5 = (void *) 0x0 (gdb) up #2 0x0000003578d66716 in QMetaObject::activate(QObject*, QMetaObject const*, int, void**) () from /usr/lib64/libQtCore.so.4 I am willing to debug this case, but I do not know the sources at all.
