Application: kmail (4.14.6)
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.19.0-12-generic x86_64
Distribution: Ubuntu Vivid Vervet (development branch)

-- Information about the crash:
It has crashed twice in five minutes, so I chose to follow through with the "Crash Reporting Assistant". This session I had added a Gmail account. It crashed once when pressing okay on the top level configuration dialog, and once when changing folders in the left-hand pane of the main window.  The KDE desktop and applications on this installation of Kubuntu 15.04 beta have been generally unstable.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
