Bug report #13799
'Merge' algorithm can't recognize GeoTiff layers

I wanted to mosaic two DEM layers using Processing toolbox 'Merge' algorithm but it failed to create resulting dataset. I checked the log in Log Message Panel and it says: '_2015-11-10T11:08:39 1 Data source is invalid ()_' but my layers are simple GeoTIFF files. I also attached a screenshot about log of the algorithm (merge_alg_02.png).
Is there something wrong with GDAL?
