Can you describe in more detail what, exactly, you mean when you say the "browser crashes?" Do all of the "crashes" seem similar in some way? If so, what is it? If not, how do they differ?

$ konqueror --profiles
$ konqueror --profile filemanagement & # <-- to start the filemanager as a child process
