 It works e.g. with the landuse layer from the North Carolina dataset.

 But when I use my own rasters I’m getting errors like the one below:

 {{{
 r.category.trim input=test at Tata qgis=C:\Processing\test cat.txt
  Traceback (most recent call last):
  File “C:\Users\alistair\AppData\Roaming\GRASS7\addons/scri
  pts/r.category.trim.py”, line 197, in
  sys.exit(main(*gs.parser()))
  File “C:\Users\alistair\AppData\Roaming\GRASS7\addons/scri
  pts/r.category.trim.py”, line 123, in main
  CCAT = map(int, CCAT)
  ValueError: invalid literal for int() with base 10:
 ‘24.0862’
 }}}

 I'm pretty sure that it is an integer raster.
 It was made with v.to.rast using an attr column that db.describe confirms
 contains integers.

 These are the categories:
 {{{
 r.category map=test at Tata
  24 cat2
  46 cat1
 }}}

 And if I load the raster into QGIS it describes it the same as the NC
 landuse i.e. "Thirty two bit signed integer", and "No data value" =
 -2147483648
