Code Issues Activity Actions

Spreadsheet: Change paste action's enabled state on clipboard change

Browse source 
Previously, the paste action was always enabled and always assumed that
anything was selected, which led to a crash by clicking the paste action
right after the application startup.

This patch will automatically enable/disable the paste action depending
on whether a selection exists (it usually does, except on the app launch
and after adding a new tab) and if the clipboard mime type is a text/
group.

So no, you can't paste an image into the app anymore, even though this
mostly froze the app before...
