wget http://download.berlios.de/xfce-goodies/thunar-archive-plugin-0.2.4.tar.bz2

results in downloading a file named "from_sourceforge".

When the same link is used interactively, the downloaded file is correctly named thunar-archive-plugin-0.2.4.tar.bz2.

The behaviour breaks automated download and build systems such as sbopkg.

Here's a screen-scape showing what happens:
