First I would try to find what is causing that error. PyGObject
doesn't open the typelibs nor the .so themselves, but does it through
gobject-introspection.

In order to find out what is calling dlopen, put a breakpoint there
with gdb and check out the backtrace.

I believe you want to do something similar to what libsecrets does, so
you may want to check out its sources or ask Stef Walters.
