They also work with the reportbug text/urwid UIs, the issue only occurs with the reportbug GTK UI for some reason. If I add some debugging to the SystemPage execute function from the gtk_ui.py file to print the xdg-email command that is run under a VTE terminal. I then copied the command into a GNOME Terminal and it ran there just fine. I then commented out the self.terminal.spawn_sync call and the black screen in the reportbug UI stayed around instead of closing immediately. Then I tested subprocess.run() instead of Vte spawn_sync and it worked. Then I tested the mutt reportbug option and it worked fine. Then I tested setting the reportbug mua option to the evolution MUA (which xdg-email opens normally) and it worked fine. Then I hacked the code to append "; sleep inf" to the command being run and xdg-email worked fine. Then I tried "; sleep 0.1s" and it did not work. 0.5s does not work but 0.9s does work. So I think there is some sort of race condition within VTE or something. BTW, I think the GTK UI should not be running the MUAs under a VTE terminal unless the MUA is marked as needing a terminal. Same for any other commands it runs under a VTE terminal. For xdg-email probably most of the commands that runs don't need a terminal. BTW, I think that reportbug shouldn't be running commands via the shell and definitely shouldn't be using bash even if shell really is needed. BTW, while debugging I saw this deprecation warning: <stdin>:1: DeprecationWarning: Vte.Terminal.spawn_sync is deprecated https://developer.gnome.org/vte/unstable/VteTerminal.html#vte-terminal-spawn-sync -- bye, pabs https://wiki.debian.org/PaulWise
