Version:           0.8.1 (using 4.3.1 (KDE 4.3.1), Gentoo)
Compiler:          x86_64-pc-linux-gnu-gcc
OS:                Linux (x86_64) release 2.6.30-gentoo-r4

Steps to reproduce:

1) Search for some city (e.g. kiel)
2) Quickly append and remove characters to / from the query (possibly try hitting enter each time you modified the search query)
3) After several attempts you should see marble crash with a backtrace like the one below

Note: This seems not to be related to the particular map view. Perhaps problems with different queries scrolling the globe too quickly to different locations?
