--- Comment #6 from chocolateimage <chocolateim...@protonmail.com> ---
I am on linux mint (may cause old packages) and in the appimage version it also
does not work. I found a fix for this issue:
in src/abstractmodel/abstracttreemodel.cpp
change function "int AbstractTreeModel::rowCount(const QModelIndex &parent)
const" to this:
int AbstractTreeModel::rowCount(const QModelIndex &parent) const
{
if (parent.column() > 0) return 0;
std::shared_ptr<TreeItem> parentItem;
if (!parent.isValid())
parentItem = rootItem;
else {
int parent_internalId = int(parent.internalId());
if (m_allItems.count(parent_internalId) == 0) {
return 0;
}
parentItem = getItemById(parent_internalId);
if (parentItem == nullptr) {
return 0;
}
}
return parentItem->childCount();
}
