Gnome Context Menu

[Christoph Georgi]

Hi,

If got the follwing problem with the "right mouse button" context
menu: I installed gpdf and used the "right mouse click -> open with
other application" option to tell Gnome to open *.pdf files with gpdf.
Gnome is now opening my pdfs with gpdf by default. However, I
uninstalled gpdf again (purge) but Gnome still tries to open my pdfs
with gpdf. Furthermore, I would like to remove gpdf (and other
applications) from my right mouse context menu.. Can anyone tell me
how to change the default application for pdfs and how to edit the
context menu?!

Thanks

Christoph
