OK, so I'm not entirely sure testing the one item case is even possible since the crash happens when switching from a fullscreen window (which implies that there are at least two windows). However, this is what I did, and everything was successful (no crashes).
1. Boot a Lubuntu Lunar ISO, and install the patched Openbox into it. 2. Log out. 3. Log in, but with a plain Openbox session. No desktop, no panel, no LXQt, just Openbox. 4. Open a terminal emulator, and run "firefox &" followed by "diswon <pidOfFirefox>". Then close the terminal emulator. 5. Fullscreen Firefox with F11. 6. Attempt to "switch" out of Firefox with Alt+Tab. No crashes occur. 7. Open Wikipedia. 8. Right-click on a link and click "Open in new window". No crashes occur (this is what was able to reliably trigger the crash before). 9. Switch between the fullscreen and non-fullscreen window with Alt+Tab. Still no crashes. 10: Fullscreen the second Firefox window and switch between them with Alt+Tab. Still no crashes. 11: Take both Firefox windows out of fullscreen and switch between them. Still no crashes. I did a bit more than that, but that should cover the one-item and two-item test cases. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to glib2.0 in Ubuntu. https://bugs.launchpad.net/bugs/2011751 Title: openbox crashed with SIGABRT To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glib2.0/+bug/2011751/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
