cannot open a pdf file

[masfia]

Binary package hint: file-roller

when I double click or press the "open" button in an archive containing a pdf file the result is that nothing happens.
If I press the "open with..." button and is showed the "open" dialog, the dialog show me in the upper pane (available applications) three applications: "adobe reader", "kghost view" (that I have unistalled but is still present), "evince".
Finally, when I select one of the installed applications ("adobe reader" or "evince") and click the button "open" It's all OK.

Because the double click or pressing the "open" button don't work?
Because this strange operating?
Can I delete the unistalled application "kghost view" from the upper pane (the button "remove" does not work) ?

Hi

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it without more information. I am not able to reproduce this bug in 8.04 unfortunately. Can you provide us more information/inputs on this.
