I am using Ubuntu 11.4 with Gnome 2.32.1 and nautilus 22.214.171.124. Every once in a while nautilus seems to tag some folders as "taboo" in the sense that whenever I try to open them, the whole window closes down.
Restarting the computer is of no help, the same folder remains taboo. However, after a couple of days, the problem may disappear spontaneously, so it is not 100% reproducible, just some 90%. I still can have a look at taboo folders by using a terminal window or the midnight commander, and those folders and their files seem to be quite ok. Thus, I assume that Nautilus is broken or infected or simply buggy, but I do not know how to repair it.
Does somebody know how to remedy the above problem?
