I am unable to paste from KeePass¹ (mono/winforms) to WebKitGTK. I can paste from KeePass to other GTK applications just fine. Examples: * paste username/password from KeePass to fields on a webpage displayed with Epiphany 3.8 => nothing * paste username/password from KeePass to the URL entry in Epiphany 3.8 => works * paste username/password from KeePass to fields on the Google/Facebook login page in gnome-online-accounts => nothing * paste username/password from KeePass to Gedit, copy from there and paste into WebKitGTK => works I tested this on Fedora 18 and 19 Alpha with the same results.
