Re-posting reply here for tracking:

I could reproduce your issue. there is a problem, but your PR doesn't solve it, it 's just a side effect of it. the problem is that the setting is overwritten by its default value when it shouldn't be basically all values are overwritten by their default tbh that may be tricky to solve quickly, so what I'd suggest you is simply make a gef restore to force reloading the .gef.rc

This PR fixes the visible side-effect rather than the root cause of the issue. One possible way to address this would be to force gef restore once the setting gef.extra_plugins_dir is changed to a different value. This will fix the issue this PR tries to fix, because the setting is originally correctly set by the gef-extras.sh install script.
