        <pre>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</pre>
