           Version: Git (master)
          Platform: Gentoo Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash

KMail was just about to finish downloading new E-Mails when it crashed.
Because i started KMail in a Konsole-window, the last messages in the
konsole-window read

[warn] epoll_wait: Bad file descriptor

Before that, KMail sometimes shows a message saing that Akonadi is not running
and on the konsole-window i read s.th.
akonadicore_log: Socket error occurred: "QLocalSocket: Remote closed"
and afterward akonadi gets restarted.

The crash after download is relatively new, the closing of akonadi also happend
with Qt-5.6.9999 (gentoo-live-ebuild).

The crash can be reproduced sometimes.

Reproducible: Sometimes

Steps to Reproduce:
1. Open Kmail
2. Check mails
3. crash


Expected Results:  
Kmail should not crash.

The part of akonadi not running happened also with Qt-5.6.9999.

 (Compiled from sources)
Qt Version: 5.7.0
