bug#1798: 23.0.60; easypg incompatible with tramp?

[trentbuck]

I tried to open a remote, encrypted file /ssh:foo:/bar/quux.txt.gpg.
When I do, it immediately pops up with this buffer:

    Select recipents for encryption.
    If no one is selected, symmetric encryption will be performed.  
    - `m' to mark a key on the line
    - `u' to unmark a key on the line
    [Cancel] [OK]
    <list of keys>

It looks like easypg is trying to encrypt the file, instead of opening
it!  I think this problem is because tramp starts by reading the
remote file in and writing it out to /tmp/<gibberish>.gpg.

I tried this to tell epa NOT to encrypt tramp's cache files, but it didn't work.

I can't reproduce it here.  Could you please try:

M-x debug-on-entry epa-file-write-region

to figure out which function calls `write-region' handler?

I've just checked with Emacs 24.0.50, it works without any
tweakings. Could you, please, retest?

Thanks, and best regards, Michael.

No reply, so I close the bug. In case you disagree, you could reopen it.

Best regards, Michael.
