Indeed, following error occurs:

I have found the root cause I believe:
> when I visualize datasets from a data library, the data is not displayed.
> Getting them from the source history gets displayed is OK
> Importing them from a data library in a history, and displaying in trackster works

It's likely that the job creating the summary tree failed for some reason. Can 
you please look through your database for summary tree jobs and see if they 
have any standard out/err that could provide insight into the problem?

Thanks,

Hi all,


Since the last updata of Galaxy, I was not able anymore to view newly added 
tracks to existing or newly created visualisations.

In the webhandler, I have traced down this error:
