            Bug ID: 119633
           Summary: Opening password protected xlsx file from "Recent
                    Documents" list in Calc causes memory leak
           Product: LibreOffice
           Version: 6.1.0.3 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: zhx at cnzhx.net

Description:
Memory taken by soffice.bin keeps increasing when a password protected .xlsx
spreadsheet is opened through "File" -> "Recent Documents" list in Calc. I use
openSUSE Tumbleweed with KDE Plasma 5 (X version, not Wayland). LibreOffice is
from the official repository. This problem has been there for more than one
month (maybe two or more).

Steps to Reproduce:
1. Create a new spreadsheet in Calc,
2. Save as .xlsx format and check "Protect with password",
3. Close the document,
4. Open the saved document through "File" --> "Recent Documents" and input the
password,
5. Open KSysGuard to watch the increasing memory usage of soffice.bin

Actual Results:
Memory taken by soffice.bin keeps increasing from several hundred MB to several
GB until I kill the process.

This issue also occurs within a newly created system account.

Expected Results:
The document was used to be opened almost instantly after correct password had
been entered.


Reproducible: Always


User Profile Reset: Yes
