            Bug ID: 127045
           Summary: Calc FILEOPEN hangs for seconds without noticeable cpu
                    load when opening .ods file
           Product: LibreOffice
           Version: 6.2.6.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: 61.1p57 at gmail.com

Description:
any .ods file, even an empty file just created. safe mode doesn't help. Opening
Calc directly is fine, opening .xlsx is fine, so I suspect it's something to do
with loading a .ods file. 

I'm using 6.3.0-2~bpo10+1 on Debian, but also reproducible with the AppImage
build

Steps to Reproduce:
1. Open new spreadsheet
2. Save empty spreadsheet
3. Close program, open the saved spreadsheet

Actual Results:
hangs for seconds without noticeable cpu load

Expected Results:
open almost instantly


Reproducible: Always


User Profile Reset: Yes



Additional Info:
if I use File->Close after step 2 instead of closing the program, the
spreadsheet can be re-opened almost instantly

Version: 6.2.6.2
Build ID: 684e730861356e74889dfe6dbddd3562aae2e6ad
CPU threads: 2; OS: Linux 4.19; UI render: default; VCL: kde5; 
Locale: zh-CN (zh_CN.UTF-8); UI-Language: en-US
Calc: threaded
