./python -c "memoryview('test')"
Segmentation fault

I compiled Python 3.0 with 
$ ./configure --with-pydebug --enable-unicode=ucs4

I've used gdb to trace the segfault:

Program received signal SIGSEGV, Segmentation fault.

Committed revision 57193.  This problem was due to not initializing the new BufferError properly.  Travis mentioned this in his post to python-3000.
