LibreOffice Viewer crashes when screen is rotated. It may happen as when rotating is in first time after launching the app, but after some time. You can see it on video: https://www.youtube.com/watch?v=GD67wf5Rwtg All settings are by default after installing the app. Phone: Samsung Galaxy S3 Duos, Android 5.1.1 (Cyanogenmod 12.1.1)
I can confirm with Version: 5.1.0.0.alpha1+ Build ID: 4d4bc50

Build from 16.10.2015 (http://dev-builds.libreoffice.org/daily/master/Android-ARM@24-Bytemark-Hosting/2015-10-16_08.17.54/): problem is resolved only in "LibreOfficeViewer-strippedUI-debug.apk" (ID: 7ad750a). In "LibreOfficeViewer-debug.apk" (ID: 8dc648d) the app crashes again (I don't know, is there the patch on it).
8dc648d is older and doesn't contain the fixes.
Works in Version: 5.1.0.0.alpha1+ Build ID: 8dc648d
