Screenshot of the problem in Calc

Attachment #162592 from bug #134316 is a simple empty Calc table with header
set.
Attachment #162593 is the same file saved as xlsx.
If Tools – Options – Calc – Defaults – Enable very large spreadsheets is
enabled (without this the crash does not happen):
* Going to Print preview of the XLSX version shows the preview with No Data –
this is fine.
* Typing any data to the sheet, like “a” to A1 and going to Print preview /
trying to print crashes Calc with this on the console:

LibreOfficeDev 7.0 - Fatal Error: multi_type_vector::position#1750: block
position not found! (logical pos=1048600, block size=2, logical size=1048576)

Steps to reproduce:
    1. Tools – Options – Calc – Defaults – Enable very large spreadsheets
    2. Open Attachment #162593
    3. Type something to the sheet, go to Print preview or Print

Actual results:
Crash.

Expected results:
No crash.
