Hi,

Thanks for the report. I can reproduce it, but I do not see a real
use case for a newline inside a label.

A label that ends with a newline works fine. That is what a script
gets when it reads the label from a file. The file only breaks when
the newline is in the middle, with text on both sides. I cannot see
that happen by accident as well.

Do you mind sharing with us the use case of having a newline in
a backup file?

Thanks,
Shihao
