Public bug reported:

Upstream discussion: http://www.kdenlive.org/forum/mlts-sdl-module-not-
found-0

kdenlive refuses to start when freshly installed, because it doesn't parse the 
output from melt -query correctly. The somewhat cryptic error message is "MLT's 
SDL module not found.".
This happens because kdenlive expects melt to print its feature list to stderr, 
but the latter prints it to stdout.

Until this is fixed, the inital setup can be made working by renaming
/usr/bin/melt to /usr/bin/melt.real, then creating the shell script
/usr/bin/melt with the following contents:

#!/bin/sh
if [ "$1" = "-query" -o "$1" = "--version" ]
then
exec /usr/bin/melt.real ${1+"$@"} >&2
else
exec /usr/bin/melt.real ${1+"$@"}
fi

(Courtesy of the thread on kdenlive.org)

After the first run, the shell script can be deleted and melt.real
renamed back to melt.

This affects melt 0.7.4-3 combined with 0.8-4build1.
