"Unable to save settings" error

I have 2 machines.
With the first machine, DataGrip runs correctly, but on the second machine, I am getting an "Unable to save settings" error

In the log file, I see
2017-06-16 14:35:51,962 [   6969]   WARN - mponents.impl.stores.StoreUtil - Save settings failed
java.lang.RuntimeException: java.io.IOException: /home/paul/.DataGrip2017.1/config/options not found

However, the directory does exists
$ ls -la /home/paul/.DataGrip.1/config/
total 13

If I delete the options directory, when I run DataGrip again, it automatically gets recreated and then I get the same error again (Unable to save settings)

I cant see any difference between the setups. I had wondered if there was a difference with the JDK, but they are the same versions

Has anyone seen this before, or have any ideas what to try? I have tried both 2016.3.2 and also 2017.1.4 and both exhibit the same issue.

Thanks
