   The C code actually does this, but the lisp handler breaks this.
   I will install a patch shortly.

Interesting.  Now I was able to load four remote files, without any
problems.  No crash, no base64 error messages.  Then I do 
M-x customize-group RET auto-revert to check whether I did not
accidentally change some option.  Crash.

Here is a C backtace.  I will try to produce a Lisp backtrace
manually.  This time I will not try any more to come up with the name
of a function object that has no name.  I hope xbacktrace does not try
to that too, but anyway, it again does not work.
