remotepasseval

[J. Tull]

i'm trying to use the "remotepasseval" option to assign passwords in
the offlineimap rc file. I wrote a python function that uses gpg2 to
echo the password. That function is the following:

    import re
    import subprocess as sb
    def bashcmd(command):
        p = re.compile(r' ')
        sb.call(p.split(command))

and in the rc file i put:

    remotepasseval = bashcmd('/usr/bin/gpg2 -dq --no-tty my_pass.gpg')

but offlineimap crashes, below is the output, and note that it prints
in plain text the decoded content of my_pass.gpg ===================================
