Hello, I can also confirm this behavior on 3.0.5-1. However, I have been able to resolve this issue as follows:
1) Install iceweasel-gnome-support and desktop-file-utils. 2) Add "x-directory/gnome-default-handler" to the list of MimeTypes supported by kfmclient_dir (To do this, in /usr/share/applications/kde/kfmclient_dir.desktop, change "MimeType=inode/directory;" to "MimeType=inode/directory;x-directory/gnome-default-handler") 3) Run update-desktop-database (as root) I don't know what changes could be made to the package, though, since I don't know how to specify priorities of applications providing support for the same MimeTypes (the order in /usr/share/applications/mimeinfo.cache stores this, but it is clobbered every time the cache is regenerated). If this change were made in the konqueror package, it might disturb simultaneous installs of kde and gnome. Maybe these tidbits of wisdom should be collected in /usr/share/doc/iceweasel/readme.kde or something? Antonio
