My SourceTree app for Mac is up-to-date(2.3(65))
When I press the display-off shortcut(control + shift + eject), the SourceTree app is crashed.
The shourtcut doesn't mean sleep mode, just display off.
However, it works fine in my iMac environment.

iMac env.
iMac 5k Late 2014
Memory : 24GB
Mac OS X El Capitan 10.11.4

Both use Korean language.

Thank you.
