Apparently in  Windows10, C:\users\<user>\Appdata\Roaming\gnupg\gpgsm.conf
This doesn't seem to be the issue, apparently just listing keys can take a
while.  I may pursue it on their mailing list.

The very bad news is the delay frequently cause claws to crash on me,
specifically when trying to click through a bunch of emails to find the one
I'm looking for.  I think its an issue of trying to update the signature
icon after I've moved on to a new message.  I can reliably produce it by
rapidly clicking as few as 3 signed emails in a row.  The logs say only:

smime.c:223:Checking S/MIME signature
mimeview.c:1212:waiting a while
summaryview.c:3817:TIMING : 0s023ms
sgpgme.c:465:data 0B29FC8C (2596 5915)
mimeview.c:1220:mimeview.c:1220:killing checker thread
killing checker thread
<EOF>

I thought one time I got a GTK container doesn't exist error, but I can't
seem to reproduce that.  Being on windows I'm not sure I can get much
additional information out of the crash.  Is there a windows debug build?
