QListView infinite recursion

In a very specific scenario, when refiltering a model, I receive a stack overflow with the QListView. My basic setup is

QListView -> QSortFilterProxyModel -> QStandardItemModel

It appears that when I refilter with a specific string, the list view goes into infinite recursion layout out its children. This seems to happen when the scroll bars are turning on and off. This functionality seems to be happening in

QAbstractScrollAreaPrivate::layoutChildren()

In one call, the needh is true and needv is false. This triggers changing the size of viewport, which calls updateGeometries() and then layoutChildren(). The next call to layoutChildren() has needh to false and needv to true, which again triggers a resize of the viewport, and so on.

hbarpolicy = Qt::ScrollBarAsNeeded
vbarpolicy = Qt::ScrollBarAsNeeded

I'm sorry I don't have a repro case. This appears to happen only with a specific filter string here and our current set of data. Turning uniformItemSizes to off fixes the problem here, as does changing the scrollbar policies to "always on". Feel free to contact me for any additional information. A portion of the stack trace is as follows:
