I am new to the video editing software kdenlive and tried to use it to edit a large avi`` file. I added theaviclip and started a job to find the scenes in this avi. Halfway through the clip (after 30 minutes or so),kdenlive` suddenly crashed.

How can I fix this problem?

Additional information related to my questions will be given below once they are asked. As I have no idea whether the issue is related to Ubuntu, the desktop, kdenlive or the avi file, I cannot be more specific at this point.

Additional information

  • Sometimes the program outputs the following:

    Unable to start Dr. Konqi

    But there seems to exist no package which might solve this problem.

When attempting to debug issues such as this I would first run them in a shell so that you can get access to any logging messages that the tool might be throwing when it fails either before, during, or after it has crashed.

$ kdenlive |& tee kdenlive.log

From a shell. Try this and capture any output that may get generated into the file kdenlive.log. Going further you can use strace to see what system calls kdenlive is making which might help give you hints as to where the issue might be occurring.

$ strace -o kdenlive_strace.log kdenlive
  • I will do this as soon as I have the opportunity and post the relevant output (or what I think is relevant).

  • Sure thing. If the logs are long you can post on pastebin.com and then post the link here.
