Since a recent calibre update one of my custom columns is suddenly broken and is displaying:

EXCEPTION: cannot import name EvalFormatter

for all books. It's a "column built from other columns" using this template:

Code:

{tags:'in_list($, ",",
   "^topic:",                 re_group($, ".* ?topic:([^,]+).*", "[[$]]"),
   ".* ?technical \(",      re_group($, ".* ?technical \((.+?)\).*", "[[$]]"),
   ".* ?technical$",        "",
                                   "")'}

I don't know which update broke it, but I last noticed it working a few months ago. I have other columns "built from other columns" which do still work, for instance one using this template:

Code:

{:'list_re(author_links(":", " & "), " & ", ".*?([^:]+):?$", "\1")'}

so it's something to do with the specific template that seems to be suddenly causing a problem.

Any help greatly appreciated!

Mike
