gnome-terminal crashed with SIGSEGV (detaching tabs)

[JP Foster]

Binary package hint: gnome-terminal

I detached a tab when I only had one tab. This created one window with one tab and one window with no tabs.
I then used the menu to detach a tab from the window with no tabs.
This causes all gnome-terminals to crash.
I know this is kind of a pathological thing to do, but I was surprised that all the terminals died.
If there is no open terminal in a window dethach tab should be greyed out probably

Thanks for your bug report. Please try to obtain a backtrace http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report. This will greatly help us in tracking down your problem.

Backtrace didn't work here is the output of it. Looks from the stack trace that the first thing to fix is to check system->priv is valid before dereferencing it. (from stacktrace source.txt)

there's no backtrace there, closing this report for now, thanks.

Happens reproduceably for me on Hardy Beta x86_64; reopening and attaching backtrace.

JP Foster: the reason the backtrace didn't appear to work is that by default, gnome-terminal will exit if another terminal process is already running. So the process your debugger created detected your open terminal process, switched to it, and exited. To prevent this, run it from the debugger with the --disable-factory.

[Pedro Villavicencio (pedro)]

thanks, may you install the following packages: libglib2.0-0-dbgsym, libgtk2.0-0-dbgsym and get a new trace? thanks in advance.

[Tim Lesher (tlesher)]

Attached.

[Pedro Villavicencio (pedro)]

thanks you will forward upstream.
