For whatever reason, aerc fails to show a message in the list, and instead of showing the contents for the columns that I have defined (pretty much standard: index-columns = date>12,name<17,flags>4,subject<50,labels<*), I get the following in the name column: " template: column-name:1:2: executing "column-name" at <index (.From | names) 0>: error calling index: reflect: slice index out of range".

The (redacted) message is here: https://paste.sr.ht/~inwit/d470bedd4ea6417bb82dc29d17c161be86c65a45
