There was an openSUSE Packman packaged update to kde4-kdenlive yesterday from version 0.7.3-0.pm.1 to 0.7.3-0.pm.2, for openSUSE-11.1 which included updates to some other libraries. I applied the change to my 32-bit openSUSE-11.1 laptop's KDE-3.5.10 desktop, and it immediately broke kdenlive, yielding the error :
A Fatal Error Occured
The application Kdenlive (kdenlive) crashed and caused the signal
I suspect the update was to take advantage of a new version of libmlt/mlt (from 0.3.8 to 0.4.0) but it did not work for me.
I have my software configuration manager (smart package manager) setup to save every rpm I install, so I rolled back to the previous version. This was a bit tricky because of the various dependency packages that I had to also roll back. I ended up typing "rpm -qa --last" to see what rpms I had installed, and even then I had to do some detective work to roll back the dependencies. In the end I rolled back to
* kde4-kdenlive-0.7.3-0.pm.2 to kde4-kdenlive-0.7.3-0.pm.1.i586.rpm
* re-install libmiracle1-0.3.8-0.pm.1.i586.rpm
* libmlt1-0.4.0-0.pm1 to libmlt1-0.3.8-0.pm.1
* re-install libvalerie1-0.3.8-0.pm.1.i586.rpm
* mlt-0.4.0-0.pm.1 to mlt-0.3.8-0.pm.1.i586.rpm
kde4-kdenlive now works again on my openSUSE-11.1 PC with kde-3.5.10.
