I know there is some setting in adobe acrobat reader to switch of monitoring of the
X paste buffer (which I couldn't find now) and it seems one really wants that. I was very surprised today when I tried to paste a password using
pwsafe and observed the following:
$ pwsafe -p fandango
Enter passphrase for /home/nion/.pwsafe.dat:
You are ready to paste the password for hosts.fandango from PRIMARY and CLIPBOARD
Press any key when done
Sending password for hosts.fandango to acroread@hostname via CLIPBOARD
So apparently acrobat reader is stealing my password from the X paste buffer if the application is running. Especially given all the javascript, malicious pdf file kungfu that is around these days I of course don't find this very amusing.
Lesson learned: Use xpdf whenever I can even though it really lacks features :/
