Application: marble (1.8.20 (1.9 Alpha))
KDE Platform Version: 4.13.60 (Compiled from sources)
Qt Version: 4.8.6
Operating System: Linux 3.10.25-gentoo i686
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
Trying out the navigation features of Marble, using the OpenStreetMap map view.  Set the start and destination points about 1 mile (1.5km) apart with a sinple and obvious car route between them.  The "Routing" panel found a route from OSRM and displayed it on the map.

I used the View - Info Boxes - Routing menu to show the floating box.  I wasn't sure what was the function of the four buttons here, since there are no tool tips, so I clicked each of them in turn.  The "zoom out" and "zoom in" buttons worked as expected;  the "globe" button toggled on and off but apparently did nothing.  The leftmost "information" button displayed a message box with the abbreviated message

  Caution: Driving instructions may be incomplete or wrong...

              [X] Show again                     [ OK ]

I left the "Show again" box ticked and clicked OK, resulting in a crash with the attached backtrace.

Possible cause:  it may be that the problem is a double or inappropriate deletion of the showAgain check box.  It is created on the stack and added to the message box, which adopts the check box as a child of itself.  After the dialogue has been exec()ed the check box will first be deleted by the 'delete messageBox' below, which deletes all of its child items, and then the automatic variable will be destroyed again when exiting the block.

The crash can be reproduced every time.

-- Backtrace:
