Crash when opening video files without audio

[Szoke]

Hi everyone,
I'm using Avidemux under Windows for years. Great product !
I installed it under Ubuntu but I get a crash when opening video files generated by VLC.
Such a test file can be downloaded from here (with its indexed picture file) :

Just drag the .avi file onto Avidemux and you get the message below.
I guess the problem is related to the absence of audio track in these files, or to some kind of empty audio stream.

Thanks a lot in advance for any help.

not here on Ubuntu 12.04 LTS 64-bit with  Avidemux v2.6.0 (r8029)
it opens even on 2.5.6 after warning message B frame. It is H264
2.6 found here: http://avidemux.org/nightly/

I forgot to give the environment details :
Avidemux 2.5.2
Lucid Lynx 10.04
Gnome 2.30.2

if you had followed above link, you would have found lucid32/ there you could download avidemux 2.6 r6984
If that does not help, next step would be building yourself:
Compiling Avidemux 2.5.x
Compiling Avidemux 2.6.x
