-- Information about the crash:
- What I was doing when the application crashed:
Run Dolphin (the only instance).
Immediately when the window appeared I moved the mouse over the toolbar buttons.
Their tooltips started to show and disappear.
Suddenly dolphin crashed.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
