That sounds reasonable and that’s what I thought for my first few hours troubleshooting this. But I can consistently reproduce the same results.
Paste anything from clipboard into other installed apps > OK
Paste from clipboard into DAVdroid for ownCloud account > OK
Paste from clipboard into plain text editor to visually check output > OK
Paste URL from clipboard into DAVdroid for FastMail account > OK
Paste password from clipboard into DAVdroid for FastMail account >
Fail
Manually type password into DAVdroid for FastMail account > OK

I use very long and difficult to type passwords so I try to avoid typing them. Fortunately I don’t have to set this up very often, so I think I’ll have to call this a very strange bug and use the manual typing workaround. If anyone has any tips on how to troubleshoot this further I’d love to know why this happens.
