This is strange; no part of KDE should even remotely have been able to get removed or otherwise damaged; I will look into this as I think this is a serious problem.
I have done more testing with your packages, installing and uninstalling. Your packages are okay. The issue is with the other packages from AlienBob. It may not be his fault though. Let me explain. In Slamd64, it had libraries to run most 32 bit binaries. Perhaps his libraries were for a 32 bit system. I'm running 64 bit. I assumed Slackware64 would be he same and perhaps it is, but I don't know. Even so, installing those packages may have hosed some 64 bit binaries.
Drumar, do not worry about your packages. I think they are fine. I guess that wasn't clear in my previous post and I'm sorry if I ended up wasting some of your time!
I also tried doing builds and creating packages with slacktrack that used the configuration settings from here:
http://www.kdenlive.org/user-manual/downloading-and-installing-kdenlive/...
and here:
http://www.kdenlive.org/user-manual/downloading-and-installing-kdenlive/...
Which means I compiled mlt with:
./configure --prefix=/usr --enable-gpl --qimage-libdir=/usr/lib/ --qimage-includedir=/usr/include/qt4 --avformat-swscale --disable-mmx
and kdenlive with:
cmake .. -DCMAKE_INSTALL_PREFIX=/usr
I still have the missing SDL module problem from Bob Nutfield's screen shot's posted earlier in this forum. I'm looking forward to trying xzhayon's other suggestion about building mlt with the frei0r plugins installed. I will try this too.
I did not run ldconfig as suggested here on any of this:

I haven't gotten as far as the rest of you, but it seems those other packages from Alien Bob's site are not necessary? I'm simply following the "install from source" instructions from this site:
http://www.kdenlive.org/user-manual/downloading-and-installing-kdenlive/...
I'll let you know how the mlt package goes with the frei0r plugins installed.

Good to hear the problem is not from my packages ;-)
Right now kdenlive is being built with a fresh build of MLT with a fresh new build of frei0r. Those 3 packages will be available soon, but be warned: I have not had the time to test them out even remotely... I'll share them anyway, hoping this may give some boost somewhere somehow.
The flags you use for MLT are the same as I use; there may be something with slack64, and I can only say that I will try to build packages for those as soon as I have my system upgraded to 64-bit slack, right now it's not really an option for me due to lack of time to troubleshoot when things go wrong, holding other things back.
If you have VirtualBox or another Virtual Machine, you could try to see if the problem persists in 32-bit slack, if so it's clear the issue is not especially in 64-bit, and if not we can pinpoint it to 64-bit slack ;-)
Edit - Update: uploaded the packages; will test them out myself tomorrow!
