Application: polkit-kde-authentication-agent-1 (5.4.1)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-18-generic i686
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed: I started the synaptic package manager and, as usual, it asked me for my superuser password. I copied the password from KeepassX and when I right-clicked the password field... Crash!

-- Backtrace:
Application: PolicyKit1 KDE Agent (polkit-kde-authentication-agent-1), signal: Segmentation fault
