Did you get the gmic_gimp_qt from the gmic.eu site? ie one of the linux packages. These are for either debian sid or ubuntu cosmic and produce that error. Ubuntu 18.04 (bionic) uses an older version of QT. Up to you if you want to mess around with QT versions but IMHO not a good idea.
I keep compiled versions of gmic_gimp_qt for Ubuntu 18.04 (bionic) here:
https://www.gimp-forum.net/Thread-gmic-g...untu-18-04
Try one of those. Working ok here in Gimp 2.10.10 and kubuntu 18.04
