Just wanted to know if its me or someone else is having problems with the "show file" option for a pdf and the adobe reader plugin.

Everytime I try to use the show file command it prompts me to a "launch application window" It used to work with ubuntu 11.04.

Also Everytime I open a pdf using the adobe reader plugin it crashes showing a black window with no pdf, If I deactivate the option then I can see pdfs normally with Okular but with okular I cant open new documents as Tabs.

Is it any fix for this?
