The filetypes are TL.TeXworks.edit, TL.PSView.view,
TL.DVIOUT.view and TL.bitmap2eps.convert, with corresponding

I already mentioned a garbled searchpath for TW, but nothing else
comes to my mind.

For next year, we could simply append `.2012' to these filetypes.
Association with an extension can either be as primary filetype or
as an entry in the OpenWithProgIds list, in which case it is
available via the right-click menu.
For 2011, overriding the filetype of an extension moved the former
primary filetype to an OpenWithProgIds entry. For 2012, we could
always override the unversioned TL... filetypes in this way. I am
pretty sure that it is no big deal.

Looking around on a Ubuntu live-cd system, it appears that gnome
implementations of Windows inconveniences are slightly saner than
the originals; I found e.g. a text file
and a file /usr/share/applications/eog.desktop with:

TeXWorks apparently does not rely on absolute paths, but composes
