I have the same problem. When running gnome-appearance-properties (from the gnome-control-center package), in the visual effects tab I switch the visual effects state from normal to none. I guess my gnome-terminal is unable to handle this change.
I've installed the debug packages for gnome-terminal and for some of the involved libraries, and have attached a trace as requested. It is similar to the original trace for this report, but with the debug symbol packages my trace is more robust. Not sure of everything as to how to reproduce, I have a bunch of windows open in my first workspace, I use an xterm to open the gnome-terminal session I'm debugging, then I clone (Open Terminal on the gnome-termnal) it three times and put a terminal in each workspace. At the top of workspace one and four are open terminals. In workspace four I open gnome-appearance-properties, make the switch, and segmentation fault happens in my gnome-terminal window. It does not seem to be able to handle this switch gracefully. Trace with more debug symbols attached. ** Attachment added: "gdb trace with more debug values" https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/620522/+attachment/1512169/+files/gdb-gnome-terminal.txt -- gnome-terminal crashed with SIGSEGV in g_type_check_is_value_type() https://bugs.launchpad.net/bugs/620522 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
