Uzbl

After starting uzbl with the default example config file the browser terminates with the following msg:
uzbl: symbol lookup error: /usr/lib/libwebkit-1.0.so.2: undefined symbol: soup_session_get_feature

[echox@kaffeesatz:~] % uzbl
[echox@kaffeesatz:~] % uzbl -c uzbl/config
uzbl: symbol lookup error: /usr/lib/libwebkit-1.0.so.2: undefined symbol: soup_session_get_feature
[echox@kaffeesatz:~] !% pacman -Q libwebkit
libwebkit 1.1.10-2
[echox@kaffeesatz:~] % pacman -Q libsoup
libsoup 2.26.3-1


Here is the output if I use the verbose switch:
[echox@kaffeesatz:~] % uzbl -v -c uzbl/config
