Strange behavior with Fix Album/Photo hierarchy

Hi, I have a strage behavior with the Fix Photo hierarchy.
First, my gallery is up to date with the Git repository (install and module).
The problem I have in my hierrachy is on the first photo when I click to the next picture it switch to picture number 246...

When I try to run Fix Album/Photo hierarchy it seems to run corectly but when I return in Maintenance Tasks, I have this line:

2009-Sep-21 16:48:46 Fix Album/Photo hierarchy Stalled

and this one

2009-Sep-21 16:49:43 Fix Album/Photo hierarchy Success 2495 / 2495 rows updated

with nothing in the logs

Could someone help me?

µEdit: Sorry I post in the wrong place ...

Edit:I found the problem of organization it's ocure when I upload a video and modify it's date of capture. On a date capture organization the video appear at the right place but his number is always the last of the album

Yes 2 issues, the first is that the Hierarchy module stay at a stalled statement, and the second is, on my install a flv video seems to break the navigation beetween object (I did some test and the position of the video on the gallery isn't the problem).

I try to make a new install...

edit:All is fine after the update from git from this morning except for the stalled stattement

Already try this morning same issue: The prossess is at the same times in a stalled statue and finish a few second before
