The code it's crashing is all internal to QStandardItemModel where it removes the model from any child items of a QStandardItem. This will only break if the internal structure of a QStandardItemModel..which can't happen with the public API of QStandardItemModel Have you seen this crash since: commit 6ef80139f71f0f6ac028aef0b7fb94a9f1b8ac80 Author: David Edmundson <kde@davidedmundson.co.uk> Date: Thu Sep 12 15:26:34 2013 +0000 Do not call QAbstractItemModel methods from within QStandardItemModel Otherwise we get leaks and crashes Only other possible thought is we're manipulating the model in a different thread?
