           Summary: Crash when going "Back" or "Forward" to a deleted
                    folder
           Product: dolphin
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org

  Target Milestone: ---

SUMMARY
I was checking some folders in my downloads to decide whether or not to trash
them. After I did, I used the Back button on my mouse out of habit, and Dolphin
crashed right away. I have a 100% reproduction rate using the following steps.
May also occur on use of the back/forward UI elements in the app.

STEPS TO REPRODUCE
1. Browse to folder foo/bar
2. Click the breadcrumb navigator into foo
3. Delete bar
4. Press Back on your mouse

or

1. ''
2. Press Back into foo
3. Delete bar
4. Press Forward on your mouse
OBSERVED RESULT
Dolphin crashes immediately.

EXPECTED RESULT
Maybe upon deletion of a folder, Dolphin should clean it from the history list.
Or handling the error gracefully with a notification should be fine.
