I cannot properly reproduce the problem without the clips. Can you please provide a backtrace? From a terminal, type:

gdb kdenlive

Kdenlive will start, then you can trigger the bug. When Kdenlive crashes, go to your terminal window and type:
thread apply all bt
Then press enter until you see the full data. Copy the log to a file and paste it here or attach it to the bug report

kdenlive won't run from gdb

(gdb) run
Starting program: /usr/bin/kdenlive
[Thread debugging using libthread_db enabled]

Thanks, but the debug info is missing from your attached file. Once the program crashes, in the terminal you must type:

thread apply all bt

Then press enter until all debug output is printed, after that attach this info here

new one uploaded gdb_debug.txt

edit: did you get a chance to figure out what was causing the crash?

edit2: updated kdenlive and mlt today and it crashes as soon as I open the project (it loads to a 100 percent, shows the items in the timeline, then crashes)

edit3: with git update my project no longer close after load and only the original behavior from this bug remains.

I just commited some changes in git master that seem to fix the problem, as well as several other issues with transitions not correctly updated. Can you please test?
