Bug 425475

STEPS TO REPRODUCE
1. disable all plugins but libzipplugin, restart ark
2. download test file https://download.qt.io/official_releases/qt/5.15/5.15.0/submodules/qtbase-everywhere-src-5.15.0.zip
3. merge zip_fclose fixes https://invent.kde.org/utilities/ark/-/merge_requests/4
3. open test zip in ark, now reopen it multiple times via menu "Open Recent"

It happens because https://invent.kde.org/utilities/ark/-/blob/master/plugins/libzipplugin/libzipplugin.cpp#L66 this calls only once instead of 25361 times and m_emmitedEntries never deleted at all.

if you test debugs like this:

libzipplugin.cpp:

LibzipPlugin::~LibzipPlugin()
{
    qDebug() << __PRETTY_FUNCTION__ << thread();
    for (auto e : m_emittedEntries) {
        qDebug() << "e:" << e->name();
        // Entries might be passed to pending slots, so we just schedule their deletion.
        e->deleteLater();
    }
}

archiveentry.cpp:
Archive::Entry::~Entry()
{
    qDebug() << __FUNCTION__;
}

you will notice that only last entry from m_emittedEntries actually calls deleteLater().
