If you run logcheck in debug mode you'll be able to find out which file
the error is in.

For example, I added this to ignore.d.server/logcheck:

^\w{3} [ :0-9]{11} [._[:alnum:]-]+ foobar\[[0-9]+\]: test (foo test$

Running logcheck -otd gives:

[...]
D: [1108580515] cleanchecked - dir
- /tmp/logcheck.pFqP43/ignore/logcheck
grep: Invalid regular expression
[...]

I think this is what you're looking for?
