Nullpointers in 4.6 from fdroid

[dicer]

Running on Android 4.4.4 with my own server, I saw these 3 (unrelated) Nullpointers in the log. Can't really tell you why they happened anymore, but the app has been pretty unstable for me. Old notes keep showing up, crashes when I open Notes created with a normal email program etc. Maybe the stacktraces can help you to fix some bugs :)

@dicer thanks for reporting this issue. I'll have a look at it.

• Does this happen only when open notes created via an email program?
• What kind of server do you use?

Thanks

[dicer]

I accidentally had some mails in the Notes folder from another app I tested. So those got synced first. Then I played around with sync a bit and had a few crashes. So don't remember exactly.

I used Dovecot and Thunderbird (by pointing the drafts folder to the "Notes" folder)
