Cannot reproduce in kdenlive-git v15.12.0-175-g2cd3b51 master.

It might have been fixed since.

If possible, consider trying out latest git for example using http://www.mltframework.org/bin/view/MLT/BuildScripts to see if it's still present in your case.

Cmake output log

I tried to get the latest GIT, but it does not seem to work. The build replies with:

-- Detecting CXX compile features - done
CMake Error at CMakeLists.txt:24 (find_package):
  Could not find a package configuration file provided by "ECM" (requested
  version 1.2.0) with any of the following names:

    ECMConfig.cmake
    ecm-config.cmake

  Add the installation prefix of "ECM" to CMAKE_PREFIX_PATH or set "ECM_DIR"
  to a directory containing one of the above files.  If "ECM" provides a
  separate development package or SDK, be sure it has been installed.


-- Configuring incomplete, errors occurred!

I have attached the CMakeOutput.log

http://superuser.com/questions/850029/could-not-find-a-configuration-file-for-package-ecm-that-is-compatible-with-re indicates you need to install this first:

extra-cmake-modules

If something like this happens again and you don't want to wait until someone reads the issue, I recommend you enter the name or names in google, it helped in this case at least, hopefully it would work again.

Kdenlive build log

You are right! Thanks.

I also learned about "apt-file search".

And found that there are actually quite many dependencies. Could someone post the total list?

Here is mine so far: qttools5-dev qtscript5-dev libqt5svg5-dev qtbase5-dev qt5-default qtdeclarative5-dev libqt5webkit5-dev

Log attached.

Hi Grzegorz,

I can confirm that this issue was fixed shortly after the 15.12.0 release. Kdenlive 15.12.1 will be released in a few days. The bug is triggered by the context menu. As a workaround, You need to unselect the clip before trying to move it.

You can find instructions and a list of dependencies to build Kdenlive on our wiki page:
https://community.kde.org/Kdenlive/Development/KF5

You can also try our PPA that contains recent version of the 15.12 branch:
https://launchpad.net/~vpinon/+archive/ubuntu/kdenlive-testing

Hi Jean-Baptiste.

Thanks for the answer. Yes, the work-around you suggest works fine.

I actually tried to install all the dependencies from the wiki page, but still get a lot of errors.

For example:
-- Could NOT find KF5FileMetaData: found neither KF5FileMetaDataConfig.cmake nor kf5filemetadata-config.cmake 
CMake Error at /usr/share/cmake-3.2/Modules/FindPackageHandleStandardArgs.cmake:138 (message):
  Could NOT find KF5 (missing: Archive Bookmarks CoreAddons Config
  ConfigWidgets DBusAddons KIO WidgetsAddons Plotting NotifyConfig NewStuff
  XmlGui Notifications GuiAddons TextWidgets IconThemes DocTools Crash)
Call Stack (most recent call first):
  /usr/share/cmake-3.2/Modules/FindPackageHandleStandardArgs.cmake:374 (_FPHSA_FAILURE_MESSAGE)
  /usr/share/ECM/find-modules/FindKF5.cmake:110 (find_package_handle_standard_args)
  CMakeLists.txt:77 (find_package)

I guess i will just wait for the release or try the PPA. :-)
