[Reg 10.x -> 11.0.2?] Invalid rsync command generated when using custom SSH port

Using the environment variable QT_LOGGING_RULES="qtc.utils.process=true;" we see that Qt Creator runs rsync like this and it fails:

qtc.utils.process: Process 12 starting (non blocking): rsync -e '/usr/bin/ssh -o StrictHostKeyChecking=no -o Port=2222 -o User=root -o IdentitiesOnly=yes -i /home/USER/.ssh/id_rsa -o BatchMode=yes -o ConnectTimeout=10 -o ControlPath=/tmp/QtCreator-rXKOFS/cs' -av /PATH/TO/BUILD/DIR/myapp root@192.168.50.100:2222:/opt/MYAPP/myapp

Apparently, adding the port number to the final argument does not work (root@192.168.50.100:2222:/opt/MYAPP/myapp in the example above). See https://stackoverflow.com/questions/4549945/is-it-possible-to-specify-a-different-ssh-port-when-using-rsync for solutions.

(Note: The customer reports that there were no issues on an older version of Qt Creator, possibly 10.x)
