Trinity on Squeeze, Icedove brings up the dialog box for other applications here.
'edit>preferences>attachments>Portable Document Format '

The default is 'always ask, but the drop down list has Gimp, evince & other. The 
other bring up the selection box for navigating to the app.

it seems like something is missing or mis-configured.

FYI, Gnome Desktop might not work since Icedove is not a Gnome app, 
"The goal of Icedove is to produce a cross platform standalone mail application
 using the XUL user interface language."
