Description of the issue:

After regular upgrade from Golem 0.19.1 to 0.19.2 there are problems with docker machine. Golem hangs on information: Setting docker environment. In logs it is shown that docker-machine has crashed. This is not reported in GUI.

Actual result:

Golem won't launch and user does not know that something went wrong, until checking the logs

Screenshots:

Steps To Reproduce

Machine with Golem 19.1 installed is needed

1. Download 0.19.2 installer
2. Run whole installation
3. Launch Golem
4. It will hang on Setting environment modal
5. Check logs

Expected behavior

When there are encountered problems with docker it should be shown in GUI with modal.

Proposed Solution?

(Optional: What could be a solution for that issue)

If golem doesn't publish status of docker in error case, the GUI won't be able to interpret it. So it seems like a core issue not the GUI. I will make a referenced issue on Golem repo.
