Bug ID: 173732
Summary: Writer hangs on open when the document contains a
nested group while navigator sidebar is active
Product: LibreOffice
Version: 26.8.0.3 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]
Reporter: [email protected]
Description:
Writer's main thread spins at 100% CPU and the UI never becomes responsive when
opening a document that contains a nested group shape (a group containing
another group), if the Navigator is the last active deck in the Writer sidebar
and Navigator/ActiveBlock is 2811. Headless conversion of the same file works.
I found the settings by bisecting a user profile (1262 registry entries). Both
are needed; removing either one stops the hang:
<item oor:path="/org.openoffice.Office.UI.Sidebar/Content"><prop
oor:name="LastActiveDeck"
oor:op="fuse"><value><it>com.sun.star.text.TextDocument,NavigatorDeck</it></value></prop></item>
<item oor:path="/org.openoffice.Office.Writer/Navigator"><prop
oor:name="ActiveBlock" oor:op="fuse"><value>2811</value></prop></item>
Steps to Reproduce:
1. Create a fresh profile: soffice -env:UserInstallation=file:///tmp/lo-test
--headless --terminate_after_init
2. Add the two <item> entries above to
/tmp/lo-test/user/registrymodifications.xcu, just before </oor:items>.
3. Run soffice -env:UserInstallation=file:///tmp/lo-test test.docx (file is
attached)
Actual Results:
soffice.bin sits at 100% CPU and the window never becomes usable.
Expected Results:
The document opens.
Reproducible: Always
User Profile Reset: Yes
