cyrus-imapd-2.4 branch, segfault in lmtpd

[Sergey]

Hello.

I attempted to use last cyrus-imapd-2.4 branch and got error:

kernel: [8211701.360899] lmtpd[20104]: segfault at 1 ip b717f3fc sp bfd1d8e0 error 4 in libc-2.17.so[b70f9000+172000]
kernel: [8211713.497625] lmtpd[20109]: segfault at 1 ip b718b3fc sp bff849f0 error 4 in libc-2.17.so[b7105000+172000]

There is no error when commit b2dab34ccd80e7a0753bce52bc07ed18663a484f
is reverted.
