Assigned to serg because I don't see any sign of the connect engine in the stack trace. Please reassign if needed.

Comment by Alexander Barkov [ 2016-03-21 ]

Currently ConnectSE is compiled without XML support on many build machines.
We should instal libxml2 developlent package on more build machines.
