I thought again about this issue. Maybe the best solution is to simply
drop the call to rolesData from applyChangedBalooRolesJobFinished? If
any non-Baloo roles need to be updated, this will happen anyway
because we receive a signal from KDirWatch either directly or
indirectly (via KFileItemModel's itemsChanged signal) in
KFileItemModelRolesUpdater if anything interesting changes.

So I think that everything should work OK (and without infinite
recursions) if the QHash data is simply initialized to an empty QHash
in applyChangedBalooRolesJobFinished, but I haven't tested it.

Cheers,
Frank
