Bug ID: 141320
Summary: [RTF] .rtf Rich Text: broken file error due to
inserted formula
Product: LibreOffice
Version: 7.0.5.2 release
Hardware: All
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: mail-bugzi...@fluglicht.com
Description:
Using a formula in a Rich Text (.rtf) document can lead to a broken file.
LibreOffice throws a File format error, when trying to open the document
afterwards. The Reason seems to be, that under certain circumstances, a
parenthesis mismatch is produced in the file, leaving an open parenthesis from
the formula object in the rich text syntax (see reproduction steps below).
Steps to Reproduce:
1. Insert a formula (via Insert > Object > Formula)
2. Save document as RTF
3. Remove the formula using backspace
4. Undo the removal
5. Save and close document
6. Opening document throws file format error, due to syntax error in the file.
Actual Results:
File format error found at 19,7
/build/libreoffice-still/src/libreoffice-7.0.5.2/writerfilter/source/rtftok/rtfdocumentimpl.cxx:817(row,col).
Expected Results:
Keep the syntax intact.
Reproducible: Always
User Profile Reset: No
OpenGL enabled: Yes
