Description of problem:
Gpdf is unable to handle mailto: links. It tries to use "htmlview"
instead of "launchmail", or more correctly "gnome-open".
Clicking on a mailto: link in a PDF pops up an error message stating
that htmlview cannot handle that URI. Clicking on it again crashes Gpdf.
Steps to Reproduce:
1.open a pdf which has a mailto: link somewhere
2.click on that link (a error dialog appears)
3.click on that link again
Actual Results: Gpdf crashed.
Expected Results: It should have opened a (in my case) Thunderbird
composer window on the first time (which would have happend if it used
gnome-open instead of htmlview to handle URLs).
