Bug#994775: flowblade: No module name 'mlt'

[Alexandre Lymberopoulos <lymber@gmail.com>]

Package: flowblade
Version: 2.8.0.3-2
Severity: grave
Justification: renders package unusable

Dear Maintainer,

When I tried to open flowblade from terminal in my XFCE session I get the following:

FLOWBLADE MOVIE EDITOR 2.8
--------------------------
Launch script dir: /usr/bin
Running from installation...
modules path: /usr/share/flowblade/Flowblade
MLT not found, exiting...
ERROR: No module named 'mlt'

But it seems that all the dependencies are installed here. I may provide any further information upon request and guidance.

Thanks in advance and best regards, Alexandre
