It is a weird bug with "Save As ..." dialog of nautilus, affecting
apps like gedit, firefox etc. I'll try my best to describe it
clearly. In case I didn't , there is a screencast showing this
issue attached.
It happens when you save a file. Normally no matter how you changed
the destination directory you want to save that file, the file name
field should remain untouched. But now in Feisty, when you are
switching between some "special" directories, the file name will
suddenly disappear.
I've not completely figured out what kind of directories will trigger
the problem and how "special" they are. Seems the directory should
contain one or several single files of a special type. Because when
the file name disappears, I notice another file name, which is of one
of the files in the current directory, will flash away in the file
name field before the field becomes empty.
Just attach the screencast here
