Description 61.1p57 2019-08-20 08:53:50 UTC

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

looked at strace, it was probably slow IO that disappeared after rebooting... weird it didn't affect xlsx for whatever reason.
