Description
I am trying to reclassify a raster on QGIS 3.4 and I keep getting this error:
File "/Applications/QGIS3.app/Contents/MacOS/grass/grass74", line 1697 sys.stdout.write("%s\n" % grass_version) ^ TabError: inconsistent use of tabs and spaces in indentation File "/Applications/QGIS3.app/Contents/MacOS/grass/grass74", line 1697 sys.stdout.write("%s\n" % grass_version) ^ TabError: inconsistent use of tabs and spaces in indentation
I have had a look at the code and tried to fix it but then got further errors so therefore had to redownload QGIS to take a step back.

- Easy fix? changed from Yes to No
- Category changed from GRASS to Processing/GRASS
works ok on Windows and Linux.

Not a processing issue - the error is coming from grass itself, so it's either an upstream issue or a packaging issue.

Following successful cleanup of tabs / space indentation issues we executed the code and encountered a further issue.
Which, it appears was caused by a type mismatch on line 625, where the environment variable 'MANPATH' is being set to the response from subprocess.Popen('man path'), which needs to be a string but on a MAC it was a byte array.
The code now executes but fails to generate the result, reporting:-
