I am using Kdenlive on OpenSuse 11.1 64 bit, with KDE 4.2, installed from packman repository.
After I got the 0.7.3 update I went through the "Kdenlive upgraded" wizard. It showed that I needed to upgrade MLT and install recordmydesktop, which I did. Now the wizard reports that everything is ok, but the program does not start. Running it from the commandline I get the following output:
Unknown media type in type 'unknown/mime-type'
kdenlive: symbol lookup error: kdenlive: undefined symbol: _ZN3Mlt8ConsumerC1ERNS_7ProfileEPKcS4_
