Internal terminal changes environment

Opening the internal terminal of the QtCreator seems to change the values of some environment variables. Especially if the value contains an equal sign.
I encounter strange warnings, if I executed some gnome apps, like gedit, which points to the DBUS_SESSION_BUS_ADDRESS variable.
Normally the value is
DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus
which is a socket address notation and the internal terminal removes the part before the equal sign, which results in:
DBUS_SESSION_BUS_ADDRESS=/run/user/1000/bus
