This page is about the Components in Bugzilla.

Getting Started

When filing a bug, please select an appropriate Component for your report.

When you find a problem please check whether only the application where you found it is affected or whether it is a general problem for all (or at least several) LibreOffice applications. The makeup words (blends) for the subcomponents should help to distinguish these subcomponents from other meanings of the words in it.

Want to help out with bug triage? Have a hankering for database wizardry, drawing charts, or just good old word processing with Writer?

Add your name in the Adopt-a-component column below to show your commitment to triaging bugs in that category. We're aiming to see all UNCONFIRMED bugs get a response within 1 week, and be triaged within 2 weeks, so helping to identify particular individuals who can help with a certain component will give us the power we need to meet our goals!

Component Table

Note: Whenever changing Component names in the backend, make sure to test the QA/Bugzilla/Development#Dependent_Services Dependent Services, to make sure that nothing breaks

How to use subcomponents

On BugReport Details lots of subcomponents are listed with links to Bugzilla Search and Bugzilla bug submission. In the following you find hints for what kind of problems what Subcomponents should be used in the Bugzilla Subject line. In the following listing a click on the Subcomponent heading will start a Bugzilla query for that subcomponent.


Use for instance, if the configuration of LibreOffice applications (WRITER, DRAW, CALC, ...) is broken or if the Installation associates file extensions wrongly.


For all problems related to opening documents, as well as for problems when opening non-ODF file types like MS-Office, XHTML or XML, Picture formats like PNG, SVG, WMF, ... . Please generally mention the document type and if known and appropriate the Version of the document or of the software with what it has been created in parenthesis. Examples:

  • CRASH when FILEOPEN particular XLSX (MSO2007)
  • FILEOPEN particular .CDR (X6) shows ...


For all problems related to saving documents, as well as for problems when exporting to the file types XHTML or XML and Picture formats like PNG, SVG, WMF, ...


For problems with the LibreOffice Mailmerge function from menu 'Tools -> Mail Merge Wizard' or with the Form Letter function in menu 'File -> Print'.


For PDF export problems only visible in one component like Drawing, Presentation, Spreadsheet or Writer. In DRAW together with FILEOPEN for PDF import problems.


For all text direction Right To Left related problems. If the problem is limited to a particular localization or language, please add localization or language in square brackets like [AR] in the summary line. We have Bug tdf#43808 - (rtl-meta) Meta bug for Most Annoying RTL related issues.


For problems only visible during running presentation, but ok in Presentation edit mode. Also appropriate for problems visible in custom animation preview.


Use, if document contents are not shown (correctly) on the screen, but print and PDF export look ok. An additional indication might be that other LibreOffice or OpenOffice versions correctly show the contents on screen, meaning it's not a problem with the document itself.
