Created attachment 246547 [details] [diff] [review] untested patch Untested patch that should fix things here. Whenever I get around to getting a new lightning tree and confirming that this actually does fix stuff, I'll ask for review.
I would prefer to actually disable the "current-view" and "selection" radios if no view is present. Did that in https://bugzilla.mozilla.org/attachment.cgi?id=249253.
checked in with fix for bug 351957.
Verified using Thunderbird/184.108.40.206 (20061207) + Lightning/0.4a1 (2007022303). Printing for custom date range is possible, all other options are disabled.
