_______________________________________________________
Details:
Encountered this while checking bug #25332, I compiled on commit cbf1c50b.
I don't know if this issue happens with other languages - I tried several but
only found this happening on Japanese. To replicate:
1. Start Wesnoth
2. Change language to Japanese (assuming you're not already using it)
3. Open Help.
4. Observe crash.
Stack trace I got from Windows build looks like it's stuck on recursion in
help_text_area::add_text_item():
