<br>
reloadSearches() calls removeSearch() for all existing QueryServiceClients,<br>
which ends with a call to deleteLater(), so this looks ok to me.<br>
<br>
There is a theoretical scenario (existing query but no existing corresponding<br>
collection) where it would leak indeed, but that should never happen, so<br>
adding extra safety checks for that is probably not worth it. Or did you see<br>
any indication it's actually leaking?<br>
