            Bug ID: 434292
           Summary: LibreOffice is not crashing but the system kept on
                    informing me that LibreOffice had crashed
           Product: kde
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Severity: minor
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: mac-wang at sjtu.edu.cn
  Target Milestone: ---

SUMMARY
Whenever I open a file with whatever Writer or Impress or Calc, after some time
(approx. 1 min and above), when I close LibreOffice normally, it exits
normally, and the KDE Crash Handler informs me that "soffice had crashed",
because of "segmentation fault". This phenomenon appears regardless of whether
I'm editing the file. If I open and close a file in a short time, this
phenomenon will not appear.

STEPS TO REPRODUCE
1. Open a arbitrary document
2. After for about 1 min or above, close the window

OBSERVED RESULT
KCrashHandler informs me that Libreoffice ("soffice", its binary file) had
crashed.

EXPECTED RESULT
NOTHING should happen.
