  To investigate candidates for Be/X-ray binaries in the Small Magellanic Cloud
(SMC), we observed a region around the emission nebula N19 with XMM-Newton in
October 2006. We analysed the EPIC data of the detected point sources to derive
their spectral and temporal characteristics. We detected X-ray pulsations with
a period of 25.550(2) s from the second-brightest source in the field, which we
designate XMMU J004814.1-731003. The X-ray spectrum is well modelled by a
highly absorbed (NH = 5x10^22) powerlaw with photon index 1.33+/-0.27. The
precise X-ray position allows us to identify a Be star as the optical
counterpart. XMMU J004814.1-731003 is located within the error circle of the
transient ASCA source AX J0048.2-7309, but its position is inconsistent with
that of the proposed optical counterpart of AX J0048.2-7309 (the emission line
star [MA93] 215). It remains unclear if XMMU J004814.1-731003 is associated
with AX J0048.2-7309. XMMU J004814.1-731003 might be identical to an RXTE
pulsar that was discovered with a period of 25.5 s, but which is listed as 51 s
pulsar in the recent literature.
