I added the line manually, this seems to fix the stacktrace but I'm still unable to add button+ devices:

Logger: homeassistant.config_entries
Source: config_entries.py:2444
First occurred: 08:07:16 (1 occurrences)
Last logged: 08:07:16

Error occurred loading flow for integration button_plus: No module named 'config.custom_components'

This fails for me when adding a button+ integration:

• Settings
• Devices & Services
• Add integration
• Pick Button+
• => Error

That is a weird error, it seems that home assistant can't see your custom_component folder with your change. I would guess something of folder/files permission?

To be complete, I got that error when I upgraded to the 0.10 version before I made the change too. I got the stacktrace as well so I assumed that to be the issue but it seems to be an additional problem.

Rechecked just now. 0.9.0 has no issues with adding the integration, in the 0.10 I get this error with a stacktrace and after changing the source I only get this error.
