            Bug ID: 325734
           Summary: kdeinit4 segfault  when applying time setting (but
                    before also randomly when interacting with customized
                    plasma elements)
    Classification: Unclassified
           Product: systemsettings
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: rodrigoesborges at gmail.com

Application: kcmshell4 (4.10.5 "release 1")
KDE Platform Version: 4.10.5 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.16-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
Last time the crash happened when I hit apply after changing time setting.

But, actually, before I reset plasma settings and start over again my own
customization, a very similar crash would occur from minute to minute (I
couldn't install de backtracing soft. before to submit the report), apparently
for no reason.

The crash can be reproduced sometimes.
