This stack doesn't seem to look really complete, looks like there should be still something on top of Plasma::WindowThumbnail::windowToTextureGLX ?
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
possible fix: https://git.reviewboard.kde.org/r/117824/

Git commit af5a855da42c3ada2f0e802c68ad8f7c0e73b38e by Martin Gräßlin. Committed on 28/04/2014 at 08:59. Pushed by graesslin into branch 'master'. 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.
