--- Comment #1 from michelesr@autistici.org --- Seems like that the text can't be pasted when it's copied in X clipboard using `xclip -in -selection clipboard` command.
However, that used to work in previous versions of Wine (verified it by downgrading to 1.9.18)
Text copied from other programs can be pasted.
