I have had the exact same problem for the past few weeks. Started when IOS 6 came out. I can no longer open PDF attachments in either iBooks or in GoodReader. I could be IOS 6 came out.
Went to the genius bar at the downtown Portland Apple store. They didn't have a clue. Suggested I send in a bug report to Apple. Did that two weeks ago and have heard nothing.
Other threads suggest you could delete iBooks (and GoodReader) and reinstall them. Tried that. No good.
Until Apple sends an upgrade to fix this bug we're stuck.
This thread is considerably older than the advent of iOS six. Several people have reported this Open In problem after thier iOS six update, but a reset or restart has fixed it for most. Give them a try if you have not.

Restart: Hold down the power button until the power off slider appears. Slide it off. When the iPad finishes shutting down, hold down the power button again until the Apple logo appears. Apple recommends you restart the iPad at least once a month.
and then a reset if that does not work.
Reset: Hold down the power and home buttons until the Apple logo appears. The iPad will reboot. This usually takes a bit longer than a restart. takes a bit longer than a restart.
