Fix double events (#245)

[raphaelcoeffic]

This fix should be quite harmless and works for me on X9D+ simulator.

The following patch has been used to be able to test with the simu:

Fixes #245.

By the way, due to the latest .gitattributes, I had no choice but to commit the files with the fixed line endings. git forced me...

Confirmed to fix the(+) bug on X9D+.

Sorry about the line endings. I copied the unified .gitattributes across all repositories, but forgot to git pull on them before pushing the change.
