e2e-tests sometimes fail to launch Ptyxis

Start with e2e-tests/resources/SSH.py and ExecUtils.py, then inspect the e2e-tests/resources/ssh.sh invocation shown in the timeout. Reproduce the Ptyxis launch through gtk-launch in the referenced e2e environment and determine why it exceeds 60 seconds. Done means the affected e2e tests launch Ptyxis reliably without TimeoutExpired.
