Hi, I don't know whether this is off-topic, because inkscape is in extras, but here it is: Using inkscape, several functions crash the program. For example, when I press Shift+Ctrl+F to open the dialog where I can change how an object is filled or select the Keyboard shortcut help from the menu, it crashes. Some other dialogs, for example the Text + Font dialog opens correctly. I have installed inkscape via yum from extras-development and have a fully updated FC4-test2 system. When I run inkscape and press Shift+Ctrl+F, I get the following output in my console: [simon@simon ~]$ inkscape *** glibc detected *** inkscape: free(): invalid pointer: 0x0000000001cb01a0 *** ======= Backtrace: ========= /lib64/libc.so.6[0x394c56a3de] /lib64/libc.so.6(__libc_free+0x6e)[0x394c56a90e] inkscape(_ZNSt10_List_baseIN4sigc9slot_baseESaIS1_EE8_M_clearEv +0x28)[0x4ab848] /usr/lib64/libsigc-2.0.so.0(_ZN4sigc11signal_baseD2Ev +0x37)[0x35db203bcf] inkscape(_ZN8Inkscape12URIReferenceD2Ev+0x26)[0x50d9a6] inkscape(_ZN19SPClipPathReferenceD0Ev+0x10)[0x4d9bc0] inkscape[0x4d5f73] /usr/lib64/libgobject-2.0.so.0(g_closure_invoke+0xfb)[0x394dc0a27d] /usr/lib64/libgobject-2.0.so.0[0x394dc17489] /usr/lib64/libgobject-2.0.so.0(g_signal_emit_valist+0x696)[0x394dc1880c] /usr/lib64/libgobject-2.0.so.0(g_signal_emit+0x83)[0x394dc18bb7] inkscape(_Z24sp_object_invoke_releaseP8SPObject+0xa1)[0x4dfd51] inkscape(_Z16sp_object_detachP8SPObjectS0_+0xeb)[0x4e09eb] inkscape(_Z22sp_object_detach_unrefP8SPObjectS0_+0x97)[0x4e0b57] inkscape(_ZN8Inkscape3XML10SimpleNode11removeChildEP6SPRepr +0xdd)[0x5c29fd] inkscape(_ZN8SPObject12deleteObjectEbb+0x110)[0x4e2580] inkscape[0x589d40] inkscape[0x58a52c] inkscape(_Z31sp_stroke_style_line_widget_newv+0x79f)[0x58d88f] inkscape(_Z27sp_object_properties_dialogv+0x351)[0x5847a1] inkscape(_Z17sp_action_performP8SPActionPv+0x9f)[0x60fb7f] inkscape(_Z18sp_shortcut_invokejP6SPView+0x28)[0x4c0498] inkscape[0x6125d8] /usr/lib64/libgtk-x11-2.0.so.0[0x31b1f03792] /usr/lib64/libgobject-2.0.so.0(g_closure_invoke+0xfb)[0x394dc0a27d] /usr/lib64/libgobject-2.0.so.0[0x394dc178eb] /usr/lib64/libgobject-2.0.so.0(g_signal_emit_valist+0x3ce)[0x394dc18544] /usr/lib64/libgobject-2.0.so.0(g_signal_emit+0x83)[0x394dc18bb7] /usr/lib64/libgtk-x11-2.0.so.0[0x31b1fc79f8] /usr/lib64/libgtk-x11-2.0.so.0(gtk_propagate_event+0x191)[0x31b1f021c1] /usr/lib64/libgtk-x11-2.0.so.0(gtk_main_do_event+0x310)[0x31b1f024f4] /usr/lib64/libgdk-x11-2.0.so.0[0x31b2240051] /usr/lib64/libglib-2.0.so.0(g_main_context_dispatch+0x1d5)[0x394c32499e] /usr/lib64/libglib-2.0.so.0[0x394c327644] /usr/lib64/libglib-2.0.so.0(g_main_loop_run+0x192)[0x394c327b30] /usr/lib64/libgtk-x11-2.0.so.0(gtk_main+0xa1)[0x31b1f01a75] inkscape(_Z11sp_main_guiiPPKc+0x153)[0x4a7fe3] inkscape(main+0x19e)[0x4a826e] /lib64/libc.so.6(__libc_start_main+0xdc)[0x394c51c49c] inkscape(_ZN3Gtk10CellLayoutD1Ev+0x6a)[0x4a723a] ======= Memory map: ======== 00400000-00804000 r-xp 00000000 08:08 135402 /usr/bin/inkscape 00903000-00937000 rw-p 00403000 08:08 135402 /usr/bin/inkscape 00937000-01fb4000 rw-p 00937000 00:00 0 [heap] 31b0400000-31b0408000 r-xp 00000000 08:08 136971 /usr/X11R6/lib64/libXrender.so.1.2.2 31b0408000-31b0508000 ---p 00008000 08:08 136971 /usr/X11R6/lib64/libXrender.so.1.2.2 31b0508000-31b0509000 rw-p 00008000 08:08 136971 /usr/X11R6/lib64/libXrender.so.1.2.2 31b0600000-31b0603000 r-xp 00000000 08:08 137213 /usr/X11R6/lib64/libXrandr.so.2.0 31b0603000-31b0702000 ---p 00003000 08:08 137213 /usr/X11R6/lib64/libXrandr.so.2.0 31b0702000-31b0703000 rw-p 00002000 08:08 137213 /usr/X11R6/lib64/libXrandr.so.2.0 31b0800000-31b0809000 r-xp 00000000 08:08 138455 /usr/X11R6/lib64/libXcursor.so.1.0.2 31b0809000-31b0909000 ---p 00009000 08:08 138455 /usr/X11R6/lib64/libXcursor.so.1.0.2 31b0909000-31b090a000 rw-p 00009000 08:08 138455 /usr/X11R6/lib64/libXcursor.so.1.0.2 31b0a00000-31b0a14000 r-xp 00000000 08:08 140021 /usr/X11R6/lib64/libXft.so.2.1.2 31b0a14000-31b0b13000 ---p 00014000 08:08 140021 /usr/X11R6/lib64/libXft.so.2.1.2 31b0b13000-31b0b14000 rw-p 00013000 08:08 140021 /usr/X11R6/lib64/libXft.so.2.1.2 31b0c00000-31b0c0b000 r-xp 00000000 08:08 140577 /usr/lib64/libpangox-1.0.so.0.800.1 31b0c0b000-31b0d0b000 ---p 0000b000 08:08 140577 /usr/lib64/libpangox-1.0.so.0.800.1 31b0d0b000-31b0d0c00 Emergency save activated!
