arista-gtk crashes on selecting an input file

[PeterPall]

On my computer arista-gtk crashes every time I selet an input file.
Apport tells me the following: SIGSEGV in cairo_region_is_empty()

Did attach one example-file to the bug that triggers the problem for me. Seems like any file will do, though: Tested it with a .flv file and .vob files from an unencrypted DVD first.

How to reproduce the crash:
 - start arista-gtk
 - press the "create conversion" button.
 - Press the "Source (none)" button
 - choose a file
 - press OK.

arista-gtk crashes immediately.

Hi,

please provide an example file which for sure causes the crash.

Please also give a description for reproducing like:
step1
step2
...

in a way that someone who is not familiar with arista easily can provoce the crash.

Both is essential.

Thanks

arista-gtk crashes immediately.

Since segfaults occoured on my old intel atom netbook, too, the problem might be architecture-indipendent.

I have tried to reproduce.

Arista is not running properly. It got frozen on my attemped.
