Endless error message on attempt to parse wrong key

[oliora]

Attempt to load file as simple as the following cause GCL to spit error with screens and screens of error message. The only way to stop it is abort program. This only happening with Python 3 (at least in both 3.7 and 3.8). Python 2 works fine. This is not happening with the version installed from pypi but rather from the latest one (unofficial 0.6.12)
