Hi Marcos,

KiCad is not responsible for third party python plugins.  My guess is
the script in question loads wxPython build against a different version
of gtk than wxPython.  Loading gtk2 and gtk3 in the same application
will cause pcbnew to crash.  If look carefully at the KiCad build info,
you will notice wxPython support is disable
(KICAD_SCRIPTING_WXPYTHON=OFF) so you cannot run any python script that
calls wx with this build.

Cheers,

Wayne
