KDEnlive freezes after adding clip to timeline

After I import a clip and drag it into the timeline, it adds and the cursor freezes with the "grab" icon and kdenlive becomes non-responsive.

Version: 19.04.1
MLT version 6.16.0

Last thing printed to the terminal before freezing:

I'm not sure what to do next honestly... thanks for any pointers, I miss kdenlive!

Re: KDEnlive freezes after adding clip to timeline

I'm also experiencing the same issue. Did you ever manage to resolve this? My terminal output just before crashing is:

/////////// added  true
/////////// creatclipsfromlist return true

Re: KDEnlive freezes after adding clip to timeline

I got a similar output as @tmdr, but my experience is a little different.

My kdenlive works without any problems before my upgrade on 2019-12-23 -- but my previous full-system upgrade was on 2019-11-24.

After upgrading, kdenlive would freeze when clicking on another clip after clicking any clip. The console log says:

QPoint(0,149)
MUTEX LOCK!!!!!!!!!!!! setmodel
MUTEX UNLOCK!!!!!!!!!!!! setmodel
MUTEX LOCK!!!!!!!!!!!! loadEffects: 
QPoint(0,149)

By the way, I also got

[ogg @ 0x5631ac171440] Value 1.000000 for parameter 'seekable' out of range [-1 - 0]

with my ogg file. But I believe this is not the actual problem (though it's in red).

Where the first four lines

QPoint(0,149)
MUTEX LOCK!!!!!!!!!!!! setmodel
MUTEX UNLOCK!!!!!!!!!!!! setmodel
MUTEX LOCK!!!!!!!!!!!! loadEffects: 

are logged after the first click, and I can still do something on the UI. A second interaction only ends with a frozen UI and console log

QPoint(0,149)

I tried downgrading some packages (qt5-*, kio, knewstuff, mlt, frei0r-plugins), but got no luck. Probably it's with some further dependencies...


Another potentially related problem: when opening my previous project, kdenlive tells me that there are some errors in that project. Downgrading doesn't remove the error.

Re: KDEnlive freezes after adding clip to timeline

Doing more search doesn't provide more information to me, and there doesn't seem to be an existing bug report. Therefore, I opened one on https://bugs.kde.org/show_bug.cgi?id=415697

Re: KDEnlive freezes after adding clip to timeline

I resolved this issue on my machine by deleting:

~/.config/kdenliverc

which is an autogenerated file. I found another user reporting a similar but varied solution: they deleted

~/.config/kdenlive-appimagerc

which resolved their issue.

Re: KDEnlive freezes after adding clip to timeline

@tmrd I can't believe it's true... but it is!? My problem also went away...

How could that be possible...?


By the way,

~/.config/kdenlive-appimagerc

should be the config created by the AppImage version of kdenlive. So this seems to be a problem related to configuration format change?

Re: KDEnlive freezes after adding clip to timeline

I think you're right; the freeze/hang behaviour is almost certainly due to an improper parse of the config file.

In addition to improved error handling, config file versioning could mitigate this happening again in future.
