There are a bunch of projections that don't work near the
poles. I'm
not an expert, and my book on projections is home, but it's
quite
possible that your chosen projection cannot properly represent
the
poles.

Yes, I think that's the problem too. Try to use use gdal_translate to crop the
area of interest, then do what you were doing:
gdal_translate -projwin 4 58 17 45 str_4.tif germany.tif
(I understand str_4.tif is the one that includes Germany)
And then:
gdalwarp -s_srs EPSG:4326 -t_srs "+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0
+lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgri...@null +no_defs +over"
germany.tif germany_sm.tif
