--- Comment #4 from Japs <j nespolo gmail com>  2010-07-09 13:04:42 ---
Hi there, I updated my system by adding to the sources ppa:kubuntu-ppa and
running a safe-upgrade. Here is my new configuration

Application: dragon (2.0)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-23-generic i686
Distribution: Ubuntu 10.04 LTS

There are some improvements: the video is now fully played and there are no
more weird artefacts when the window self-resizes. The program now crashes
when, at the end of the playback, I click on either the play button to play
again or the close button on the title bar to close the window. Unfortunately
the KDE crash handler was unable to find the debugging packages, therefore the
following backtrace will serve very little help, I'm afraid. I send it
nevertheless, and if anyone wants to send me a few instructions on where to
find the dbg packages, I shall be glad to help.
Thank you and best regards,
Jacopo
