            Bug ID: 351483
           Summary: Got a plasma crash dialog upon login
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: jacobgodserv at gmail.com

Application: plasmashell (5.3.95)
 (Compiled from sources)
Qt Version: 5.4.2
Operating System: Linux 4.1.0-pf1 x86_64
Distribution: "Funtoo Linux - baselayout 2.2.0"

-- Information about the crash:
- What I was doing when the application crashed:

Logging into KDE after a clean reboot.

I noticed that the progress bar filled and vanished, but instead of getting
that nice fade to desktop effect, I got a black screen, and then everything
blinked in, including the crash dialog.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
