gdal2tiles_parallel only creates one file per zoom level

I'm trying to create a TMS from a GDAL VRT file. The Z folder structure is created fine however, only one X folder is created for each zoom level and only one PNG file (Y) is created inside each X folder.

I'm using Linux, 64 bit, gdal v 1.11.3
and the command I'm issuing is:

gdat2tiles_parallel.py -e -z 15 --format=PNG sp2014_b321.vrt sp2014_b321_tms/

Found out that if I set the output profile to raster -p raster, things work. It looks as thou it does not like the mercator projection
