Crash when sorting by Incl. Total in Meta Objects view

[iamsergio]

Goto to Meta Objects view, click a few times on Incl Total header to reverse the sorting. Then, click on some row, then click again a few times in "Incl Total", it crashes in:

QModelIndex RemoteModel::parent(const QModelIndex &index) const

on this line:

return createIndex(currentNode->parent->parent->children.indexOf(
                       currentNode->parent), 0, currentNode->parent);

I'm on Windows, msvc2015, gammaray master

I've seen a lot of crashes there as well.

Now with debug symbols:

gammaray_client.dll!GammaRay::RemoteModel::parent(const QModelIndex & index) Line 163 C++ Qt5Core.dll!QIdentityProxyModel::parent(const QModelIndex & child) Line 293 C++ Qt5Core.dll!QPersistentModelIndex::parent() Line 372 C++ Qt5Core.dll!QItemSelectionRange::isValid() Line 146 C++ Qt5Core.dll!QItemSelectionModel::isSelected(const QModelIndex & index) Line 1405 C++ Qt5Widgets.dll!QTreeView::drawRow(QPainter * painter, const QStyleOptionViewItem & option, const QModelIndex & index) Line 1703 C++ Qt5Widgets.dll!QTreeView::drawTree(QPainter * painter, const QRegion & region) Line 1510 C++ Qt5Widgets.dll!QTreeView::paintEvent(QPaintEvent * event) Line 1340 C++

HI, not sure if related to this issue, but for me the client crashes in the meta objects view too:

Thread 1 "gammaray-client" received signal SIGSEGV, Segmentation fault.
0x00007f4f69b70704 in GammaRay::RemoteModel::modelIndexForNode(GammaRay::RemoteModel::Node*, int) const ()
   from /usr/local/lib/gammaray/libexec/../../libgammaray_client.so.2.12.0(gdb) 

In case it helps, I'm running my application directly through GammaRay (Not attaching). This is the --version output:
