[Oxyd] [15.18][Linux] Game hangs when pasting from clear clipboard

[richese]

Hello

The game hangs when you try to paste map exchange string or blueprint string when clipboard is cleared.
By cleared I mean that there is no text or data associated with the clipboard selection.

Steps to replicate:

1. Make sure your clipboard is cleared.
   This can be done by command line clipboard manager like 'xsel'. In terminal run 'xsel -bc' to clear clipboard.
   Clipboard also should be clear right after logging in.
2. Start Factorio and focus either:
   • Map exchange string field in Map generator
   • Import string field in Blueprint Library
3. Hit Control+V to paste into selected field.
4. Game should hang and not respond to any input.

This situation can also happen if you copy / cut from an application and you close it before pasting. The application itself is responsible for providing the copied data so if you close it you are left with cleared clipboard. There are clipboard managers that keep clipboard contents after the original application is closed but I have no idea how common they are in major desktop environments.

Thanks, should be fixed in 0.15.19.
