Comment 2 for bug 57038

To begin: This bug seems to be spontaneous; I mean: some people have this bug when try to open a .wmv, with contents identified as "asf", or with a file without extension identified as some file type, or some other filetypes.
I mean that maybe you can open all your files without this problem; then maybe you'll never can reproduce this bug... a little part of the users have this problem...

Is important too, to say that people has told me (x-chat) that they solve the problem changing the extension, but I won't change the extension of the lot of jpg that I get (I'm designer!)
and finally this is a problem, then must be fixed.

Then, I'll attach some screenshots to show you the problem :)

1.png= these are jpg files
2.png= I've clicked the first image and moved to the other 3 with keyboard arrows, then automatically get preview
3.png= can't open the first file
4.png= These are other images, I don't know why some of these are normally previewed, excepting one (11.jpg)
5.png= I touch (click) the image, and get preview
6.png= Can't open the file, (even if i try with the others)

If you want, you can find me sometimes in x-chat (freenode>ubuntu-es)
Thanks :)
