Do you confirm the bug?
AFAIK this tracker is for frameworks versions of kdenlive... older versions should be reported to mantis i think.
(In reply to farid from comment #2) > AFAIK this tracker is for frameworks versions of kdenlive... older versions > should be reported to mantis i think. What do you mean?
Mantis is announced "close" (but still alive) and I cannot create any account on Mantis. Germano, what do you call "clip-text color" ? Kdenlive 0.9.10 .deb x86 UbuntuStudio: crash not reproduced with "Color Clip" and "Title clip" with 1 colored text inside.

Germano please test if this is fixed in the latest version 16.04.2 and mark as solved if possible.
(In reply to farid from comment #6) > Germano please test if this is fixed in the latest version 16.04.2 and mark > as solved if possible. As soon I get the update on my distro's repository, I will do the tests :-)
Kdenlive 0.9.x is unsupported.
I am facing the same issue with version 16.08.2 on ArchLinux! I never faced it with the previous version. Hope a soon fix :)
Ibrahim, please post a useful crash backtrace, but please only the relevant crash thread. As I don't see crashes on my Kubuntu 16.04LTS this looks suspiciously like a distro packaging error.

Sorry, but I asked to post only the stacktrace of the crashing thread. Gdb will indicate whicht thread crashed. All other backtraces are meaningless as they show these threads were idle.
I recently reported a similar report but it also affects changing color clip color: https://bugs.kde.org/show_bug.cgi?id=371416 should i close that one and post the backtrace here?
I guess I figured the issue. Last update of Arch Linux with Gnome DE has changed Gnome from using Xorg to Wayland, which is not ready to use yet, that caused Kdenlive & other applications that were reported in Arch community not to run or run buggy. So the solution is to switch from Wayland to Xorg, and to do that you have to : from GDM interface, beneath the Password Entry box there is perfrences icon ( a small icon), press on it and choose xorg, and it is supposed to work as default in the next startup. If it didn't run as default, follow this instruction : "But if for some reason that doesn't work the file the setting is being saved into when you select "Gnome on Xorg" is "/var/lib/AccountsService/users/<user_name>". Change the "XSession=" line to be "XSession=gnome-xorg". Don't mess with the gdm user file there, do it on your user file." the solution was taken from this thread : https://bbs.archlinux.org/viewtopic.php?id=218319 @Wegwerf Thanks for helping :) it is cool to see a support team who responds fast. @Farid I think this will solve your problem too.
Farid, makes sense to me to set the other report as a duplicate of this. Go for it...!
