exception during module initialization + python3

[Neal Becker]

Has behavior of exception thrown during module initialization changed with
python3?

using boost:ython, throwing a c++ exception in module initialization, I
get:

SystemError: initialization of ldpc_45 raised unreported exception

I exepected to see the string associated with exception, which gave useful
information (file not found, in this case).

I believe under python2.6 this would have happened (but I could be mistaken)
