Does it crash or just become unresponsive?

Is there a limit on the amount of data that can be stored in the clipboard
on Windows? Maybe that could be a factor. Can you paste the whole column into
another application successfully?

You need to check what sort of MIME data is contained in the clipboard. The
QClipboard documentation should have example code for this.
