Bug 386845

Application: akonadi_baloo_indexer (4.14)
KDE Platform Version: 4.14.30
Qt Version: 4.8.7
Operating System: Linux 4.10.0-38-generic x86_64
Distribution: Ubuntu 17.04

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

baloo indexing agent crashes all the time.
Very often I cannot access new e-mail - when clicking on it Kontact says something about "Folder reading ...." and nothing happened. Old e-mails are accessible.
I need to start Akonadiconsole , clear akonadi cache on malfunctioned folder, restart indexing agent and Kontact, too.
Usually it helps but not always.

The crash can be reproduced every time.

-- Backtrace:
Application: No such method 'agentName' in interface 'org.freedesktop.Akonadi.AgentManager' at object path '/AgentManager' (signature 'ss') (akonadi_baloo_indexer), signal: Aborted
