UserData(rPropertyPath) );


Expected Results:

Reproducible: Always

User Profile Reset: No

Additional Info:
The code pointed to by the profile tool is in optaboutconfig.cxx, Line 213 (
4233 Samples) -> pEntry->SetUserData( new UserData(rPropertyPath)


void CuiAboutConfigTabPage::InsertEntry(const OUString& rPropertyPath, const
OUString& rProp, const OUString& rStatus,
                                        const OUString& rType, const OUString&
rValue, SvTreeListEntry *pParentEntry,
                                        bool bInsertToPrefBox)
{
    SvTreeListEntry* pEntry = new SvTreeListEntry;
    pEntry->AddItem(o3tl::make_unique<SvLBoxContextBmp>(
        Image(), Image(), false)); //It is needed, otherwise causes crash
    pEntry->AddItem(o3tl::make_unique<SvLBoxString>(rProp));
    pEntry->AddItem(o3tl::make_unique<SvLBoxString>(rStatus));
    pEntry->AddItem(o3tl::make_unique<SvLBoxString>(rType));
    pEntry->AddItem(o3tl::make_unique<SvLBoxString>(rValue));
    pEntry->SetUserData( new UserData(rPropertyPath) );

    if(bInsertToPrefBox)
        m_pPrefBox->Insert( pEntry, pParentEntry );
    else
        m_prefBoxEntries.push_back(std::unique_ptr<SvTreeListEntry>(pEntry));
