KrViewer: closing the last tab with escape crashes Krusader

[zigi]

Binary package hint: krusader

When I close one file opened within KrView with ESCAPE, Krusader crashes. May be it is caused by QT4.5.

$krusader -v
Qt: 4.5.0-rc1
KDE: 4.2.00 (KDE 4.2.0)
Krusader: 2.0.0-SVN "Mars Pathfinder"

$krusader
krusader(24499) UserAction::UserAction: Initialisising useractions...
krusader(24499) UserAction::UserAction: 24 useractions read.
Calling appendChild() on a null node does nothing.

I am also affected by this bug. I'm on updated Jaunty, x86-64. The bug occurs mostly (not always, let's say with 80% probability) when I open an XML file and then close the viewer by Esc key, krusader crashes. Backtrace:
