DEV-20171230 Send/Share crashes from within preview

[rullzer]

1. Open an image
2. Open menu
3. Click Send/Share
4. 💥

All works as expected if I click on the share icon in the file list next to the same image.

There is no release version apk file for version 2.1.0. How can I have the apk file with this bug?
