Hi Juan Rafael,
I suggest you to read the description of the "Rasterize (vector to 
raster)" algorithm [1].

If you select "Pixels" as "Output raster size units", then the following 
parameters "Width/Horizontal resolution" and "Height/Vertical 
resolution" are intended as width and height (in pixels) of the output 
raster, not as resolution.

Anyway, the algorithm log shows that the value entered for the width and 
height parameters was 0, and not 1. So the output raster would be a 0x0 
raster and thus the underling GDAL rasterize tool failed [2]:
***
Input parameters:
{..., 'HEIGHT' : 0, ..., 'UNITS' : 0, 'WIDTH' : 0 }
GDAL command:
gdal_rasterize ... -ts 0.0 0.0 ...
GDAL command output:
ERROR 1: Wrong value for -ts parameter.

It seems to me the log doesn't show any weird character.

Best regards.
