I got a crash because find_newline called buf_charpos_to_bytepos with
a charpos bigger than BUF_Z. It was in an Rmail summary buffer.
Unfortunately I spazzed and the process got destroyed.

This is bug #15841, it was fixed in bzr revision 115138. Your build
is older than that, so please update soon to avoid this nasty
problem. In the meantime, you can turn off cache-long-scans by
default, or even rebuild after doing that in buffer.c.
