[Serusers] ser + serweb: unable to register user

[Socrates]

Hi, 

We have been running SER 0.8.14-2, reliably so far. We've recently
added SERWEB, but with little luck. When a user responds to an e-mail
to confirm his/her registration we get the following on SER+SERWEB's
console:

fifo_add_contact(): expires == 0, giving up ul_add(): Error while
adding contact "XXXX" in table 'aliases'

Any idea what might be wrong?

Thanks,
