--- Comment #11 from Benjamin Robin <benjarobin+kde at gmail.com> ---
Reverting 9d90c0edac91b "fixes" the issue, but this part of code is not the
problem.

I did add some tracing, and there are 2 allocations that are realized in
QImageData with the following properties:

===> nbytes: 8589934552, bpl: 4, w: 1, h: 2147483638, d: 32
===> nbytes: 42949672760, bpl: 20, w: 5, h: 2147483638, d: 32

A detailed callstack:

 - frameGeometry parameter of Plasma::FrameItemNode::reposition() is equal to
"1x2147483638+5+5"
 - In FrameSvgItem::updatePaintNode() of framesvgitem.cpp:561, The local
variable QSize frameSize(width(), height());is equal to: wd=11 and
ht=-2147483648
 - Looks like it is related to imagePath=widgets/scrollbar  prefix=slider
