The problem is an invalid unref in atk, causing crash in at-spi2-atk with invalid g_object_unref() call, on an already freed object. I filled an upstream bug [1] with a fix for it already. The backtrace from the FAF report is: Thread 1 (Thread 0x7fb800d11a80 (LWP 25909)): #0 0x00007fb7f5c864ad in g_type_check_instance_is_fundamentally_a () from /lib64/libgobject-2.0.so.0 #1 0x00007fb7f5c68537 in g_object_unref () from /lib64/libgobject-2.0.so.0 #2 0x00007fb7eaa68b5d in expiry_func () from /lib64/libatk-bridge-2.0.so.0 #3 0x00007fb7f598ceed in g_timeout_dispatch () from /lib64/libglib-2.0.so.0 #4 0x00007fb7f598c4c9 in g_main_context_dispatch () from /lib64/libglib-2.0.so.0 #5 0x00007fb7f598c818 in g_main_context_iterate.isra.21 () from /lib64/libglib-2.0.so.0 #6 0x00007fb7f598caea in g_main_loop_run () from /lib64/libglib-2.0.so.0 #7 0x00007fb7f74f94b5 in gtk_main () from /lib64/libgtk-3.so.0 #8 0x0000000000403de1 in main () https://bugzilla.gnome.org/show_bug.cgi?id=783245 No longer reproducable Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHBA-2017:2100 FOr the record, as found in bug #1717000, the change causes leaks of AtkAObject-s in other than Evolution (like in gnome-shell, which the new bug is filled for). |
