Version: 2.2.4 (using KDE 4.2.4) Compiler: gcc/g++ (Gentoo 4.4.0 p1.1) 4.4.0 OS: Linux Installed from: Gentoo Packages Umbrello crashes when I try to save changes after removing two use cases from “Use case view” (using “Delete” command in right-click menu) which does not present on the sole “Use case diagram” (because was removed from it before) and after I “Save” a file. I get this backtrace: Application: Umbrello UML Modeller (umbrello), signal SIGSEGV Thread 1 (Thread 0xb5cc7710 (LWP 27436)): #0 0xb8096424 in __kernel_vsyscall () #1 0xb6350f20 in nanosleep () from /lib/libc.so.6 #2 0xb6350d64 in sleep () from /lib/libc.so.6 #3 0xb796daa8 in ??

I have no debug versions of qt and kdelibs (I have debug version of Umbrello only), so gdb does not provide good enough backtrace: Program received signal SIGSEGV, Segmentation fault.

I wonder why even when you have debug symbols for umbrello the backtrace is mostly empty. Are they properly installed? (or may be the backtrace is qt+kdelibs only?) Thanks
They are properly installed (I've just checked it out) and backtrace (which just popped up in KDE when Umbrello crashed) might be of qt+kdelibs.
After rebuilding some libs with debugging support and disabling stripping of umbrello's binary I have got more informative log: Application: Umbrello UML Modeller (umbrello), signal SIGSEGV Thread 1 (Thread 0xb58e4710 (LWP 30043)): [KCrash Handler] #6 0x083420b7 in UMLFolder::saveContents (this=0x864f7d8, qDoc=@0xbfeb65d8, qElement=@0xbfeb6308) at /var/tmp/portage/kde-base/umbrello-4.2.4/work/umbrello-4.2.4/umbrello/umbrello/folder.cpp:204 #7 0x0834244c in UMLFolder::save (this=0x864f7d8, qDoc=@0xbfeb65d8, qElement=@0x8a2be30) at /var/tmp/portage/kde-base/umbrello-4.2.4/work/umbrello-4.2.4/umbrello/umbrello/folder.cpp:234 #8 0x08342c5e in UMLFolder::saveToXMI (this=0x864f7d8, qDoc=@0xbfeb65d8, qElement=@0xbfeb64c8) at /var/tmp/portage/kde-base/umbrello-4.2.4/work/umbrello-4.2.4/umbrello/umbrello/folder.cpp:241 #9 0x083b23de in UMLDoc::saveToXMI (this=0x864f0a0, file=@0xbfeb6644) at /var/tmp/portage/kde-base/umbrello-4.2.4/work/umbrello-4.2.4/umbrello/umbrello/umldoc.cpp:1351 #10 0x083b60b3 in UMLDoc::saveDocument (this=0x864f0a0, url=@0x864f0d4, format=0x0) at /var/tmp/portage/kde-base/umbrello-4.2.4/work/umbrello-4.2.4/umbrello/umbrello/umldoc.cpp:637 #11 0x0839ccd9 in UMLApp::slotFileSave (this=0x865a850) at /var/tmp/portage/kde-base/umbrello-4.2.4/work/umbrello-4.2.4/umbrello/umbrello/uml.cpp:969 #12 0x083a4131 in UMLApp::qt_metacall (this=0x865a850, _c=QMetaObject::InvokeMetaMethod, _id=144883248, _a=0xbfeb6908) at /var/tmp/portage/kde-base/umbrello-4.2.4/work/umbrello-4.2.4_build/umbrello/umbrello/uml.moc:226 #13 0xb65f5a58 in QMetaObject::activate () from /usr/lib/qt4/libQtCore.so.4 #14 0xb65f5da5 in QMetaObject::activate () from /usr/lib/qt4/libQtCore.so.4 #15 0xb67e54d5 in QAction::triggered () from /usr/lib/qt4/libQtGui.so.4 #16 0xb67e65c8 in QAction::activate () from /usr/lib/qt4/libQtGui.so.4 #17 0xb6ce75ee in QToolButton::nextCheckState () from /usr/lib/qt4/libQtGui.so.4 #18 0xb6bec89b in ??

The backtrace looks related to the one in bug 168273. Thanks
do not crash in release 4.11.5
