I had no problems. The log files were where it said they were.Not sure why you can't find a log file, though. I'll run through thing son Ubuntu for Windows and see what happens for me.
I take it you are looking for them under Ubuntu, not Windows?
One thing I did notice was that the Ubuntu on Windows is painfully slow at running this.
When building one set of picons (if they're just for one user there's no point in building more than one set) this was the Ubuntu on Windows log:
That took 7m 25s.Log file located at: /tmp/tmp.8PQ25iVTnG.picons.log

When running it directly on Ubuntu on the same hardware (I have a dual-boot laptop) this is the log:

I know Windows has to emulate things, but that indicates something on Windows is just slowwww... (file-system access?).
