Created attachment 103293 [details] backtrace Application: kdenlive (16.12.0) Qt Version: 5.7.1 Frameworks Version: 5.29.0 Operating System: Linux 4.8.15-300.fc25.x86_64 x86_64 Distribution: "Fedora release 25 (Twenty Five)" -- Information about the crash: - What I did before: I created a Kdenlive project (v. 16.04 or 16.08, IIRC) with Fedora 24 Workstation on Gnome. It was using some video files from a partition that I mounted every time I wanted to work on the project (sudo mount /dev/sda1 /mnt). Yesterday I made a fresh install of Fedora 25 Workstation (I installed both, KDE and Gnome, but I kept using Gnome). Today I was reordering some of my files in the partition. - What I was doing when the application crashed: When opening the project again, it asked me to provide the new location of the files, I chose the new folder and then it crashed. - Related issue? Few minutes before it worked ok (it could get the files from the new location correctly), but was constantly crashing when clicking on a title clip in the library panel. The output on the console was this one: QXcbConnection: XCB error: 8 (BadMatch), sequence: 39197, resource id: 50332215, major code: 130 (Unknown), minor code: 3 Not sure if these two issues are related.
A valgrind log would be nice. Also, if possible, please attach the project file (xml file) you see this crash with.

Created attachment 103567 [details] Project file Here is the XML project file. I don't know exactly how to generate the valgrind log. However, I couldn't reproduce this error any more.
So can we close this issue?
I couldn't reproduce this error any more, so yes, you can close it. Just wanted to upload the backtrace in case it was useful for you.

Thanks for your help, the thing is if we cannot reproduce it the devs can't fix it. If it ever happens again please let us know. Cheers :D
