Dear CCP4 developers,

Forgive the posting here, but I can't find the correct contact details for 
Graeme Winter…

I have just downloaded the latest version of XIA2 (0.3.3.3 build 3479) and 
tried to integrate a dataset.  The program fails with the following error…

>>>

However, if I run exactly the same command set through an earlier version 
(0.3.3.1 build 3479) I have no problem…

Likely spacegroups:

Reindexing to first spacegroup setting: I212121 (h,k,l)

>>> NB: the program terminates normally.
