Does it crash when JFFS2 is built-in but _not_ used as root?
I mean, does it not crash up to the point you mount it and try to access 
it?

If so something is really weird.

CAn you try with and without CONFIG_JFFS2_FS_WRITEBUFFER?

Looking at the changelog between v2.6.12 and v2.6.13 for fs/jffs2/ I 
don't see anything that could obviously explain the above.

Can you try the 2.6.12 code for JFFS2 in your 2.6.13 kernel?
