vaillant@lightning:~$ openshot

Hi,
The problems comes from your version of MLT which seems to be buggy. You should update at the last version (0.7.6) and see here to see how to update : https://bugs.launchpad.net/openshot/+bug/879507

[johannesgrillet (johannesgrillet)]

Thank you. I updated libmlt++3 libmlt-data libmlt4 melt python-mlt3 after adding the repository as explained on the above link. I was happy to work a while without crashing openshot, but he did it again (see log, ubuntu 10.10, synaptic installation, openshot 1.4.0). What do I need (to do)?

[johannesgrillet (johannesgrillet)]

I mean Ubuntu 11.10. attached a shorter terminal transcript of two crashes. The problem is very similar to http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=645399 (crashing when moving the timeline to check content of video).

I also tried the localefix (http://www.remastersys.com/forums/index.php?topic=1702.0) but failed due to an MLT-independency.

[Olivier Girard (eolinwen)]

In this case, I am thinking that you have only like solution to .....wait an update of MLT.
Today, I've just finished an update of MLT and he is now in the version 0.7.7. You should check until this bug (and some others) will be resolved. I 've seen too that a new correction bug's version of Kdenlive will be out quickly and I am sure that this regressions bugs are not strange to this situation that we know currently.

Status changed to 'Confirmed' because the bug affects multiple users.
