Description Daniel Vrátil 2015-04-14 15:20:10 UTC 
Run kmail, wait for it to start, then try to run start another kmail process.

Actual result:
The new process crashes right at start

Expected results:
Window of the already running instance is activated and the newly started kmail process quits.

Comment 1 Laurent Montel 2015-04-15 05:59:08 UTC 
I confirm it.
It's a bug with kontact unique application.
It's not totally ported yet.
Comment 2 Daniel Vrátil 2015-05-18 11:03:23 UTC 
Fixed in master by https://git.reviewboard.kde.org/r/123773/ and https://git.reviewboard.kde.org/r/123774/ (porting KontactInterface away from KUniqueApplication).
