Not really, except something wrong happens in Python. The plugin manager window is C++ itself, however, when you click to open it, it calls that Python function from your first error message to fetch Python plugins from the repository. When the plugin list is ready, Python calls back the C++ API to open the window.
Apparently something bad happens in Python when it tries to fetch new plugins. Are Python plugins generally work for you (hopefully you had some enabled, at least Processing or DB Manager)? Does the Plugins->Python console seem to work? Another idea is maybe running QGIS from the command line would give some debug messages.
