Sentry Crash Report:

Description Eike Hein 2017-08-03 08:14:31 UTC 
Application: kmail (5.6.40 alpha1)
 (Compiled from sources)
Qt Version: 5.9.2
Frameworks Version: 5.37.0
Operating System: Linux 4.11.8-300.fc26.x86_64 x86_64
Distribution: "Fedora release 26 (Twenty Six)"

-- Information about the crash:
- What I was doing when the application crashed:

KMail was running over night and crashed when kdesrc-build reinstalled kde-pim. The backtrace clearly shows a KDirWatch used to list grantlee themes.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 3 David Faure 2018-04-22 08:58:29 UTC 
Git commit f3da346dcecd7d8ff83582a24b0bcc4ce01d4302 by David Faure.
Committed on 22/04/2018 at 08:58.
Pushed by dfaure into branch 'Applications/18.04'.

Fix GrantleeTheme::ThemeManager being leaked.

Summary:
When a Viewer was deleted, its ThemeManager was kept alive.
So it would still react to KDirWatch (when installing files) and it
would try to update a menu (QActionGroup) that was deleted with the
viewer.
FIXED-IN: 18.04

Test Plan:
KMail, Enter to open separate viewer, Alt+F4, (uncommitted)
debug output shows that now the ThemeManager is deleted, while it wasn't before.
