Bug 280132

Application: polkit-kde-authentication-agent-1 (0.99.0)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic-pae i686
Distribution: Ubuntu 11.04

-- Information about the crash:
I had been attempting to kill a process from the S"ystem Actifvity" window.  I was asked for authentication, which I provided.  Nothing seemed to happen.  I tried again, and got the notification of the crash.  This may be a duplicate as indicated, since there were two efforts to kill a process within a short period, and possibly the second authentication request window was never seen.

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