<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">this is somehow not equivalent to the other variant (ignores silent/uninited) - the iterator should perhaps go with a map pointer/reference to stress this (and as a matching map usage is required anyway)</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">my understand is that silent/unintended was dead code for these cases as it only iterated over the startups and that if it's in startups it's not in silent or unintended. I'll re-check that.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">yep, unintended and ignored do not matter in that case as it's either in startups or in silent_startups or in unintended_startups:
if (update_P) { // change: without any new: first
//qDebug() << "adding uninited";
uninited_startups.insert(id_P, data_P);
} else if (data_P.silent() != Data::Yes || flags & AnnounceSilenceChanges) {
//qDebug() << "adding";
startups.insert(id_P, data_P);
emit q->gotNewStartup(id_P, data_P);
} else { // new silenced, and silent shouldn't be announced
//qDebug() << "adding silent";
silent_startups.insert(id_P, data_P);
}</pre>

This is similar to the change ... just for more cases. If the API was
used with ::checkStartup it could happen that an item got removed from
the startups while iterating the list of startups. Thus the data
corrupted resulting in a crash when getting a similar crash.
In this case the code now uses erase instead of remove to have a valid
iterator.
