Two problems I have: 1. KMail main window, message display section. There are no headers (to, from, subject, date...). If I open a separate window by double-clicking the message, there are still no headers. 2. If I open menu "View -> Headers", next sub-menu is not displayed. This bug first appeared in Apps 16.04.0. Since in another distribution I also use KDE in (Arch), there is not such problem with same KDE Applications version, I report here, not to KDE Bugzilla. Reproducible: Always
Install kdepim-addons.

Thanks for your ultra-fast reply. It worked. Not closing the bug since it looks like a missing dependency to me.
Will be fixed in 16.08.0 by messagelib containing a standard header and kdepim-addons a selection of fancy headers. *** This bug has been marked as a duplicate of bug 581464 ***
