[QGIS-Developer] SAGA algorithms not usable in Modeler

[matteo]

Hi devs,

I tested several SAGA algorithms within a Modeler. Even with very very
simple models (one layer - one algorithm) every SAGA algorithm I tested
I get a stacktrace.

If someone can confirm this I think this could be a serious trouble
(Tested on Linux - QGIS master compiled version)

Cheers

Matteo
