What steps will reproduce the problem?
1. python gdal_tiler.py --tps -q -r -s -p xyz 11325_3.KAP

What is the expected output? What do you see instead?

Please provide any additional information below.

I was thinking that it was a problem in gdal itself but when testing the same 
file with this I can see the rendered tiles:

gdal_translate -of vrt -expand rgba 11325_3.KAP temp.vrt
gdal2tiles.py temp.vrt

Since they are using the same libs, I guess that the problem is in

You should try it without "--tps".

I believe gdal2tiles.py doesn't use it either.

There is an error in the source data.

Right.
Can't it automatically fallback to no "--tps" if it fails?

The problem is that I am batch processing a lot of files and I don't know when 
I need or when I don't need to use "--tps".

Maybe there could be an option to specify the order that we would like to try: 
"--someoption tps,nontps" (ie, try tps first; if it fails, automatically 
fallback to non-tps)

Perhaps you would not need '--tps' at all, would you?

Geotransform should be quite fine for BSB rasters.
