Replacing the default Konsole with Byobu in desktop icons

After more than 10 years of launching Konsole from a desktop icon which uses a Promptread routine for interactive Perl menus which writes a prompt to STDOUT and then reads the user's response from STDIN, this routine is now failing in an infinite write loop. I tried using the other Perl approaches, Readline, and Term::ReadKey with the same result, even autoflushing the output buffer after each prompt write. Nothing works I am now getting this error while pausing in the Perl debugger before the prompt, indicating that Konsole is somehow infected: X Error: BadWindow (invalid Window parameter) 3 Major opcode: 20 Minor opcode: 0 Resource id: 0x7a00187 Apparently this shows up from time to time, but nobody has resolved it. If I use other terminal emulators, the problem goes away. In particular, Byobu replaces the look and feal of Konsole, so I would like to use it. Is there a way to change settings in the icon creation dialog with its terminal option to make byobu the terminal default instead of Konsole?
