okay, so this line in the trace of the valgrind's recorded 19th event (the peak
of memory consumption)
->99.77% (5,243,953,552B) 0x61A98C3: QImageData::create(QSize const&,
QImage::Format) (qimage.cpp:145)
asks for 5GB of memory using a function QImageData::create

the half of which comes from the KMainWindow::event function
->49.87% (2,621,440,000B) 0x5189FA2: KMainWindow::event(QEvent*)
(kmainwindow.cpp:862) 

and other half comes from an unknown function
| ->49.87% (2,621,440,000B) 0x61A9C79: UnknownInlinedFun (qimage.cpp:799)
which leads down to QCoreApplication::notifyInternal2
->49/87% (2?621?440?000B) 0x6A06AE7^
QCoreApplication^^notifyInternal2(QObject*? QEvent*)
(qcoreapplication/cpp^1134)

so possible culprits? I think these things come from qt framework so I need a
second opinion on these.

To add to this the dolphin opens in the end (after a minute or so) and works as
expected with normal memory consumption, it's in the beginning when it starts
to consume all of system's memory
