Description Frederik Schwarzer 2008-12-21 19:03:11 UTC 
Version:            (using Devel)
Installed from:    Compiled sources

1. mount an external media
2. press F9 to close places
3. browse to some local folder
4. click the icon on the most left of the breadcrump and hold it until the menu opens
5. choose to unmount the external media

Here this atempt crashes dolphin before being able to unmount the media.

SVN commit 929876 by ervin:

Not sure what caused this crash as I can't reproduce it.
In any case checking the access pointer before calling teardown() can't
hurt.
