Breadcrumbs doesn't handle moved and deleted directories

[joshas]

1. Open directory in file panel.
2. Go back up.
3. Delete, move or rename that directory.
4. Clicking on directory title in breadcrumbs will show "Error changing working directory" error message.

Should breadcrumbs handle directory updates and remove non existing ones from breadcrumbs path? As it might be complicated to implement, I'd like to suggest using "classic" breadcrumbs functionality, where breadcrumbs path ends with current directory and history is not displayed.
