Hi. Sorry for my English. But:
1. Krusader don't work as default file manager.
2. If you change the default file manager for Krusader in plasma applet Device Notifications displayed icon of Dolphin, the clique was trying to run Krusader, but nothing happens.

(Gentoo amd64, KDE 4.2.0)

I use also Krusader as file manager and I did not know about possibility to set up it as default file manager. And maybe you can ask at http://www.krusader.org/phpBB/ too ..Just my two cents.

BTW Krusader is based on KDE technologies, it is KDE related app, so maybe wrong category
Other KDE software would be maybe more suitable. But this is for moderator to resolve..

May be yes, may be no

Try this: System settings - Default Applications - File Manager
