Comment 1 Marco Martin 2014-04-16 17:52:47 UTC 
This stack doesn't seem to look really complete, looks like there should be still something on top of Plasma::WindowThumbnail::windowToTextureGLX ?
Comment 2 Hrvoje Senjan 2014-04-18 14:52:47 UTC 
that was the whole bt that had any significance; i got it only once or twice, will see do i get it with yesterday's tooltip fix commit

Git commit af5a855da42c3ada2f0e802c68ad8f7c0e73b38e by Martin Gräßlin.

Discard window thumbnail pixmap after texture got destroyed by SceneGraph

If the window holding the WindowThumbnail item goes away the texture hold
by the node is destroyed but our bound window pixmap is not yet freed.
This results in incorrect state the next time the WindowThumbnail is
shown.

To get back into a clean state discardPixmap() is called if there is no
texture but a bound low level pixmap.
