Frameworks Version: 5.32.0
Operating System: Linux 4.9.16-desktop-2.mga6 x86_64
Distribution: "Mageia 6"

-- Information about the crash:
- What I was doing when the application crashed:
 from default :
- I added week numbers, 
- make some try to display date and seconds, apply then revert,
- added fr-fr holidays, applied, browse de calendar, but no holidays appear.
Leave the config, ask to save changes, ok. Crash.

The crash can be reproduced sometimes.

Looks close to Bug 377936, but backtraces beginings are different (I don't know what makes backtraces similar enough)

Comment 2 David Edmundson 2017-03-23 12:01:19 UTC

Yeah, they're the same just one person had a different build of Akonadi.
