            Bug ID: 346752
           Summary: kdeinit5 crashes when attempting to set encryption
                    passcode
           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: reimu at hakurei.pw

Application: kdeinit5 ()

Qt Version: 5.4.1
Operating System: Linux 3.19.0-15-generic x86_64
Distribution: Ubuntu 15.04

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

A notification regarding software updates brings up a window labelled "Update
Information - KDE Daemon", which has an option "Record your encryption
passphrase" (for ecryptfs). Clicking the "Run this action now" button causes
the window to hang for a second before crashing.

The crash can be reproduced every time.

-- Backtrace:
Application: kdeinit5 (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
