While looking through the Kmail options today, I saw that for large attachments, Kmail can send the file to dropbox and generate the link. But when I try to authorize Dropbox to Kmail, the website that's loaded doesn't work. I can type in my username/password, but the website doesn't recognize that I've typed anything and so the button to authorize it never becomes ungreyed. If it helps solve what the problem is, the placeholder text that tells you what to type into the box remains superimposed over what I'm typing. In normal operation on websites, this text disappears when the user starts typing. Reproducible: Always Steps to Reproduce: 1. Go to config for attachments 2. Try to configure dropbox 3. Type in username (I think it's email) and password 4. Try to click on the button to authorize it Actual Results: Can't click button because it (apparently) doesn't know I'm typing Expected Results: Should allow me to authorize dropbox.
This bug has never been confirmed for a KDE PIM version that is based on KDE Frameworks (5.x). Those versions differ significantly from the old 4.x series. Therefore, I plan to close it in around two or three months. In the meantime, it is set to WAITINGFORINFO to give reporters the oportunity to check if it is still valid. As soon as someone confirms it for a recent version (at least 5.1, ideally even more recent), I'll gladly reopen it. Please understand that we lack the manpower to triage bugs reported for versions almost two years beyond their end of life.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.1 aka 15.12, preferably more recent), please open a new one unless it already exists. Thank you for all your input.
