Also affects me with fuzzer v4 and JOSM v3261.

[xteejyx@…]

Found the solution to the problem, check it works for you too:

There is an additional dependency on pyproj which is not stated on the wiki page. In Ubuntu/Debian simply install python-pyproj and python-pyproj-data to resolve this problem.

Now the question is of the next problem why it won't show any results...

[Upliner]

Have you downloaded fuzzyselect.py? What happens if you try to run fuzzyselect.py from command line?
Only thing this plugin do is run the fuzzyselect.py and return the resulting data to JOSM.

[Upliner]

I've updated the plugin so it now displays debug information in error messagebox.
