Hi,

I have been using Mew for several years.  I always get the error in
subject line, it happens when I refile the mail, and occurs very
frequently, almost one of every four times.  I then do "Ctrl-q" to
quit, if I still do "x", then the message is lost with no further
warning.  If I do "u" on the selected message, then do "o" and "x"
again, I usually don't see the same warning, and the message is
refiled correctly.

I enabled mew-debug and debug-on-error, but didn't see Backtrace
window poped up when this error happens.

This happens in mew 2.1 and 2.2, my emacs is 20.7.  One thing I think
worthy to point out is I constantly have two mew and emacs process
running on one host, one is through X from home PC and one is through
X from my work PC, though I'm not using them at the same time.  I
don't know if this affects.

Thanks,
Eric
