Different applications interact with samba shares differently, depending on how the share is mounted. I don't really understand why, but I have noticed that they do.
For example, when I use Places -> Connect to Server to connect to a file share, i.e., Gnome's Nautilus, I can save to that location with Open Office. Specifically, the share shows up "Places" column in the "Save" dialog box. On the other hand, if I try to save a file downloaded through Firefox, I don't see the share listed in Firefox's "Save" dialog box.
Knowing that Gnome Nautilus on Ubuntu uses Fuse and GVFS to mount the samba share, I experimented and found that, like if I was trying to access the share from a shell, I need to navigate into
~/.gvfs/ directory. Try as I might, I could not create a shortcut in the Nautilus Bookmarks directly to the
~/.gvfs/ directory - Nautilus always converted the bookmark into a form that Firefox ignored.
What I finally did was mount the desired share from the commandline with the
mount.cifs command. This created an entry in the "Places" column of Firefox's "Save" dialog box.
I wonder if, like Firefox, krusader is not interoperating with GVFS. If that is the case, one possible solution is to mount the samba share from the /etc/fstab or with the
