This annoying bug was fixed in Lilypond 1.4.7. What happens
is that Python sets a limit on the stacksize (in the UNIX kernel)
to be used by Python itself but unfortunately also by all programs
spawned by Python. I recommend that you upgrade to the latest stable
Lilypond release, 1.4.10. However, the fix is easy to implement also 
in version 1.4.5, just add the following lines somewhere close to 
the top of the ly2dvi script, i.e. the file specified by 'which ly2dvi'. 

       import resource
       resource.setrlimit (resource.RLIMIT_STACK, (-1, -1))

Oops! That's an even older Lilypond version. However, both these
problems should be fixed by the patch described above or by 
installing the latest Lilypond version 1.4.10.
