doc version of the buggy file
Comment 1 Milos Sramek 2012-07-13 19:05:10 UTC

There are two "signature" placeholders in the attached doc file - the right has three text lines. When loaded in LO, only second and third appear, the text "Pečiatka zamestnávateľa" is hidden. It appears, however, if the tab after "Podpis zamestnanca" (in the left signature) is deleted (and vanishes if the tab is inserted again). So, it appears that the missing text is "behind a corner".

If opened in MSO and Abiword, all three lines are displayed.

If the file is after loading in LO saved in the odf format, the line is still missing when loaded in LO, but is OK when opened in MSO and Abiword.

    fdo#45908: Cleaning up the tabs too early can cause loops
Comment 9 QA Administrators 2018-10-08 02:47:36 UTC
** Please read this message in its entirety before responding **

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)

If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword
