Since we ruled out system configuration problems, you will have to
look through the files claws-mail would read for input as returned by
$ strace -e open -o claws-mail.strace claws-mail

When it loads and the error messages are there, you would just quit
claws-mail again.

My guess is that the problem lies in some gui toolkit configuration
file, ~/.* or similar. You'll have to rule out any binary files and
grep all plaintext files with this:
$ grep -Po '(?<=")[^"]+(?=")' claws-mail.strace | while read file; do
[[ -e "$file" ]] && file -b "$file" | grep -q text && grep UTF8
"$file"; done

Get all string sequences between double quotes from the claws-mail
strace log, check if it exists and is a text file using the
libmagic-based file tool, then check if it contains your invalid
string.
You don't even deserve this solution, and you'll start sprae

cheers!
