Backtrace

Hi J-B,
when trying to add a title clip to the project from https://bugs.kde.org/show_bug.cgi?id=350556
I also got a segfault when I was dragging it from the project bin to the timeline. 
I didn't reach the timeline. The segfault occurred when I was "leaving" the project bin

Backtrace attached.
Version 15.07.0 (rev. v15.04.0-439-g0d73372)
KDE Frameworks 5.12.0

I just noticed that the aur git package screws up the version string.
It should say Version 15.07.0 (rev. v15.07.0-439-g0d73372) instead of Version 15.07.0 (rev. v15.04.0-439-g0d73372)
Same for all my 15.08 bugs.

Backtrace with adding same title twice

Hi J-B,
I think this bug is related to the 15.04 one with the transitions.
https://bugs.kde.org/show_bug.cgi?id=350276
Trying to add the same title twice triggered a segfault as well.
Backtrace attached.
Upgraded to Version 15.07.0 (rev. v15.07.0-443-g8c68703)

Backtrace with adding same title twice second try

I could narrow down the reason for the segfault. 
1. I add the first copy of the title
2. Automatically the Affine transtion gets added 
3. I add the second copy of the title right after the first one. 
4. I change the Transition on the second copy to dissolve
5. I change the transition of the first copy to dissolve - boom - segfault.

Paul, can you please try with a stable Kdenlive 16.04.2 to see whether your problem has been fixed or not? Please make sure to upgrade MLT to at least 6.2.0 too. If the bug is fixed then I would like to ask you to close this report as RESOLVED. Thank you very much for your cooperation!
