Crash when pressing 'Back' button on home screen

[Miepee]

Device Info

• Brand: Huawei
• Model name: Honor 6x (BLN-21)
• Android version: Stock, 7.0
• Alamrio version: 1.0.5, F-Droid

Steps to Reproduce

• Download the app
• Start the app and wait until it shows your alarms
• Click on the 'Back' button

I could reproduce this reliably, then I went to the settings -> about to gather the version number and now I can't reproduce this anymore. And since I didn't copy the stack trace at first, I can't post it here, sorry. Only thing I remember is that an illegalStateException was thrown.

I got this to replicate again!
Out of the blue I got a "Stopwatch: 0:00:00" notification, even tho i didn't have a stopwatch running. I clicked on it, was brought to the stopwatch screen which made the notification disappear. And pressing back a few times from here, got me the crash. Am in the state now where every time I press back from the home screen Alarmio crashes again.

Here's the stack trace (click to expand)
