Confirming this in up-to-date Precise.

• Combined screenshot of the ”System program problem detected” and ”Application problem” dialogs (50.6 KiB, image/png)

The two dialogs are very, very inconsistent: the dialog icon they use (DIALOG_QUESTION in one, the DIALOG_ERROR in the other), the dialog window title (”Application problem” vs. none), the dialog title and explanation style (brief vs. verbose), the ignore option missing from one… It’s almost as if the engineers behind the two dialogs have intentionally tried to make them as different from one another as possible. (No offence intended, I just think it’s funny although it is a genuine accessibility problem as well.) Also, one dialog seems to be minimizable whereas the other is not — though this doesn’t appear in Blair’s screenshot; it may be something introduced in Precise which the system my screenshot is from is running.

Can also be triggered by closing the dialog with mouse using the (x) button.
