As far as I'm aware there isn't a 100% working solution.  On the other hand, it probably is possible to do a bit better than one hardcoded terminal.  I happen to use KDE for the desktop and don't have said terminal installed.

I tried xdg-open, but it treats the command as a URL.

I think for a fair number of systems have the alternatives system inherited from Debian (Ubuntu, Mint, etc.) or an implementation copied from Debian (RHEL, Fedora) in which case there is a link at /usr/bin/x-terminal-emulator which will work.

Also, can the default be made to use '-e gdb -p %d'?  That syntax will work with either gnome-terminal or konsole, but the existing one does not.

Sure, please make whatever changes are helpful. I have no objection to improvements.
