I use org-capture heavily, but I do not use a template that causes this issue.
This issue was posted once again today on the org mailing list and I would vote for this to be made a blocking bug too. One useful update we get from Eric Fraga ( http://thread.gmane.org/gmane.emacs.orgmode/108289 ) is that this bug is seen only after 25.0.94 pretest. @Eric Would it be possible for you to provide a recipe to recreate this issue from an emacs -Q session? -- Kaushal Modi
