Comment 3 for bug 235427

Well if the dialog is really necessary, I would suggest something like the following:

"Evolution appears to have exited unexpectedly the last time it was run. It is possible that the contents of one of your preview panes caused this. Would you like to hide the preview panes this time? You can restore the preview panes from the View menu."

Then the buttons could be labelled "Hide previews" and "Don't hide previews".

I think this is much clearer, but it does seem like a bit of an unnecessary question. Ideally what would happen is that Evo would open as usual, but the preview pane would show a message saying something along the lines of "This message is not being displayed because Evolution exited unexpectedly the last time it was shown." With a "Click here to preview this message" button. This would be much less obtrusive, and in many cases the email being previewed is not the cause of the problem.
