The system code is unhappy about a notification:
android.app.RemoteServiceException: Bad notification posted from package org.kman.AquaMail: Couldn't expand RemoteViews for: StatusBarNotification(pkg=org.kman.AquaMail user=UserHandle{0} id=2 tag=null score=0: Notification(pri=0 contentView=org.kman.AquaMail/0x1090065 vibrate=null sound=null defaults=0x0 flags=0x62 kind=[null]))
Unfortunately there is no information about what notification it is, and what specifically is "bad".
But I *think* it's the "ongoing" notification about "checking mail in <account>".
Please try turning off AquaMail settings -> look and feel - "status bar icon".
Needless to say, I've got multiple devices with 2.3 - 4.0 - 4.4 - 5.0 right in front of me, and this notification works just fine, no crashes.
