Did you replace it with a different memory stick?  Or just left it out
of the system, so that it had 2GB less memory?  How much memory does
your system have?  I'm curious if you're crossing a 4GB boundary here,
and that's the real problem.  What I've found is that with some large
branches, the C extensions didn't work correctly.  I disabled them (by
renaming the .so's), forcing Bazaar to use the Python versions
instead.  It runs slower, but completes.  This was particularly
important during a pack operation, but I wouldn't be surprised if the
problem shows up elsewhere.

FWIW, I don't know if it's Bazaar's fault or Pyrex's fault.  I
remember looking at the code, and I believe I brought it up on IRC or
on-list... I'm not sure if that ever made it into the bugtracker
though.
