I wanted to creat a tar.bz2 archive from a file and used the commandline to do it:
$ xarchiver --add-to=xfce-trunk.ca.diff

In older versions of xarchiver 'xfce-trunk.ca.diff' was the suggested archive name in the 'create a new archive' window, but now, not file name is suggested.


After testing a bit with it, I think that the second filename is the suggested archive name:

$ xarchiver --add-to=foo --> No archive name suggested.
$ xarchiver --add-to=foo boo --> boo is suggested.
$ xarchiver --add-to=foo boo moo --> boo is suggested.

I think that foo should be the suggested archive name.
