Comment 36 for bug 210468

If the messages have stopped appearing in your logs, then the problem you're having is clearly not related to this bug, since this bug is about autofs .Trash requests. Bug comments are not really the best way to ask for help, unless it's about the bug in question. You should either file a bug against the package which appears to be at fault here, which would be either Nautilus or autofs (do you get the same behavior when you try to access the automount from the command line? That should tell you which package is likely at fault), or else maybe ask on the Ubuntu user forums.

When you do find the right place to ask, be sure to give more information about exactly which versions you're using, how your automount maps are distributed, what they contain (for example the map that contains the directory you're trying to access via Nautilus), whether it happens every single time or only when the filesystem is not mounted already (or only if you try to re-access the filesystem after automount has unmounted it), etc.
