gdb session with thread apply all bt

Konsole stops responding when I attempt to close a tab where an application other than the shell is still running. The prompt to close appears, but freezes and I can't interact with it anymore. I have to kill konsole when this happens. The traceback indicates that a deadlock is occurring in code related to an alert sound playback for the exit confirmation.

The problem doesn't seem to appear in a new user profile, but renaming ~/.config to something else doesn't fix it. For both existing and new users, I get the following in konsole's stdout just before the confirmation dialog shows up: "WARNING: Disabling PulseAudio integration for lack of GLib event loop."
