[Ubuntu] SAGA GIS segfault

[Johan Van de Wauw]

Thomas,

I can reproduce using a recent version of SAGA on Debian.
Forwarding to the saga development list.

Thread 1 "saga_gui" received signal SIGSEGV, Segmentation fault.

    at wksp_base_control.cpp:857
857 if( pItem && pItem->GetId().IsOk() )
(gdb) bt
