After downloading and saving a picture from a camera, gtkam also segfaults. These issues may be related. In any case, when saving, there is no Gtk-CRITICAL message. The following is the start of a gdb backtrace after the SEGV: #0 0x0076dacd in malloc_consolidate () from /lib/tls/libc.so.6 #1 0x0076d0ca in _int_malloc () from /lib/tls/libc.so.6 #2 0x0076c4bd in malloc () from /lib/tls/libc.so.6 #3 0x009a36f6 in g_try_malloc () from /usr/lib/libglib-2.0.so.0 #4 0x00acda01 in gdk_pixbuf_copy () from /usr/lib/libgdk_pixbuf-2.0.so.0 #5 0x06beac0a in gtk_style_apply_default_background () from /usr/lib/libgtk-x11-2.0.so.0 #6 0x06bea857 in gtk_style_render_icon () from /usr/lib/libgtk-x11-2.0.so.0 #7 0x06b6b547 in gtk_icon_set_copy () from /usr/lib/libgtk-x11-2.0.so.0 #8 0x06b6b7a8 in gtk_icon_set_render_icon () from /usr/lib/libgtk-x11-2.0.so.0 #9 0x06c97136 in gtk_widget_render_icon () from /usr/lib/libgtk-x11-2.0.so.0 #10 0x06b74851 in gtk_image_get () from /usr/lib/libgtk-x11-2.0.so.0 #11 0x06b96854 in gtk_marshal_VOID__UINT_STRING () from /usr/lib/libgtk-x11-2.0.so.0 #12 0x00a014f7 in g_cclosure_new_swap () from /usr/lib/libgobject-2.0.so.0 #13 0x00a01160 in g_closure_invoke () from /usr/lib/libgobject-2.0.so.0 #14 0x00a14bc5 in g_signal_emit_by_name () from /usr/lib/libgobject-2.0.so.0 #15 0x00a13f2e in g_signal_emit_valist () from /usr/lib/libgobject-2.0.so.0 #16 0x00a14454 in g_signal_emit () from /usr/lib/libgobject-2.0.so.0 #17 0x06c943b5 in gtk_widget_send_expose () from /usr/lib/libgtk-x11-2.0.so.0 #18 0x06b1771b in gtk_container_propagate_expose () from /usr/lib/libgtk-x11-2.0.so.0 #19 0x06b1737f in gtk_container_get_focus_hadjustment () from /usr/lib/libgtk-x11-2.0.so.0 If you run 'MALLOC_CHECK_=2 gtkam', do you get a segfault in a more useful place? Problems in malloc_consolidate indicate memory handling problems. With MALLOC_CHECK_=2, I don't get a segfault, but instead the following warning: ** (gtkam:4646): WARNING **: Invalid UTF8 string passed to pango_layout_set_text() Looks like an invalid pointer is passed around whose value is different under the non-standard memory malloc() implementation used by MALLOC_CHECK_. (BTW, the behaviour is the same for MALLOC_CHECK_=1.) I experimented a bit more and the problem doesn't seem to be related to the actual downloading and saving of the picture. If I select a picture, do File->Save Photos->Selected, and then click "Cancel" in the following dialog box, gtkam segfaults, too (and prints the warning re pango_layout_set_text() when using MALLOC_CHECK_). It appears as if the cleanup code that is executed after a dialog finishes tickles the bug. See also bug #119094. On the off-chance that 0.1.11 (released last month) fixes the problem, please could you try this package?: ftp://people.redhat.com/twaugh/tmp/gtkam/gtkam-0.1.11-0.1.i386.rpm With 0.1.11, the segfault is gone (as well as the complaint by pango_layout_set_text() when run with MALLOC_CHECK_=2); however, the Gtk-CRITICAL remains (and terminates the application). As a consequence, saving files is now fine, but saving debug information is still broken. Is gtkam-0.1.12-2 any better (in Fedora development)? We no longer ship gtkam. |
