[Qgis-developer] Processing Modeler regression Unable to open datasource of intermediate results

[Anita Graser]

Hi,

There seems to be a regression between Processing 2.9 and 2.10 where 2.10
fails to run models because it cannot find the intermediate results it
produced in a previous step. The model runs perfectly in 2.9. Bellow you
can see an example to reproduce: just chain QGIS buffer and OGR dissolve
and it fails because it's looking for a file
:\Users\agraser\AppData\Local\Temp\processing\7f77fa47bcec4799818d1f5ea41cc8a9\OUTPUT.sh
(without C: and .sh instead of .shp)

Are you already aware of this or should I open a ticket.

Best wishes,
Anita
