I recently installed Kubuntu 18.04. The terminal window no longer appears in geany.

Symbolic links in /usr/lib: libvte.so -> libvte.so.9.2800.2 libvte.so.9 -> libvte.so.9.2800.2

And in /usr/lib/x86_64-linx-gnu: libgtk-3.so.0 -> libgtk-3.so.0.2200.30

Running with run -v in gdb produces this output:
