My French is mostly read-only, so let me rephrase:
from module import *, try ... except, eval(), exec all work together to make
your program harder to understand and more likely to fail in obscure ways.

That traceback and the code you posted do not fit together. So back to
Staring at the code you posted, I think one thing you could try would be to
modify the eval() to
eval("BC", self.m_process_global, self.m_process_local)
to ensure that eval() and exec share the same namespace.
Generally speaking, I would prefer (I hope I got that right)
module = __import__("package.module", globals(), locals(), ["module"])
members = inspect.getmembers(module)
Members of the module would then be accessed via getattr():
member = getattr(module, member_name)
