Bug ID: 141603
Summary: Calc crashes with "Invalid child index" error on
different operations, but only on certain ODS
documents
Product: LibreOffice
Version: 7.0.5.2 release
Hardware: All
OS: Mac OS X (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: sma...@zoho.com
Description:
While EDITING or FORMATTING certain ODS documents only (also when these same
documents are in XLS or XLSX format), Calc crashes at different times and while
doing different operations, always popping up an alert
Libre Office 7.0 - Fatal Error
Invalid child index
The problem is present for 4-5 years now, but it doesn't happen too often (I
don't use these specific documents too often).
I can't recognize any trigger pattern. Sometimes it crashes when I directly
double-click into a cell (to edit the content of that cell) if that window
didn't have focus before double-clicking it. But not always. Sometimes it
crashes when I change font size of a cell, but not always. Sometimes it crashes
when I hit cmd+s (it crashes before saving the document), but not always.
I'm attaching one document that has this problem. I also can't say for sure
what is it in this document that causes the problem. I thought that maybe an
original document that I created was corrupt in some way, and I always used it
as a template for the other documents later. So recently I recreated a fresh
document from scratch, but the problem is still present. So, it must be about
some specific formatting or some specific content inside.
What I can think of as being different than other spreadsheets I use, is:
- the font used is Geneva
- there is a large number of rows of great height (a lot of text in one of the
columns) - usually there are about a hundred to several hundred rows all
toghether, and maybe about 20% of them of great height
- inside cell contents, a hard line break (cmd+enter) is extensively used
- inside cell contents with a lot of text (very high rows), there is a lot of
text formatting - like using bold text and different font sizes inside the same
cell
- page header has multiple lines
Steps to Reproduce:
1. Open document
2. Try editing and formating the contents (sometimes everything works fine for
hours)
3. Calc crashes out of the blue on some usual editing or formatting operation
Actual Results:
Calc crashed, everything since last save is lost
Expected Results:
Calc not crashing, editing works fine. :-)
Reproducible: Sometimes
User Profile Reset: Yes
Additional Info:
Copy&paste from About window doesn't work. See screenshot attached for version
information.
I alse tested the same document attached here under Libre Office Safe mode. It
crashed after 3-4 minutes of editing, when I clicked on Print Preview tool
button.
