Error when copy/pasting data from a LibreOffice spreadsheet

[tintou]

What steps will reproduce the problem?

1. Open a libreoffice spreadsheet
2. Copy the data directly
3. Paste it

What is the expected result?

I'm getting an exception

What happens instead?

It should just paste the data (note that LibreOffice provides several data format for copy/pasting and it seems to pick the png capture here instead of the plain text)

Please provide any additional information below. Attach a screenshot if possible.
