Yes, Jade, I get the same problem. no such key: verify. Same
behavior on acs35.theservice.de and my local installation.
Viewing the HTML source of issue-new, I see no hidden .sign field
for new_msg_id despite the call to export_form_vars -sign new_msg_id.
Did a pre-3.4.10 version of export_form_vars creep into the CVS tree
somehow?
