Dear Galaxy Users,

Since I've updated my Galaxy version I'm unable to import any dataset from my history into my data library. It returns a message of e.g. "Invalid item id (1464) specified".

I then did a complete new test installation to make sure that this problem wasn't because of the update. But the error still remains. I've included a screen shot that reports the error.

When a queried the database the dataset id does exist in the history_dataset_association table.

I went through the paster.log file and found the following warning message: Unknown library item type: <class 'galaxy.model.HistoryDatasetAssociation'>.  I'm sure this is the problem and would need to find a way to fix it.

Does anyone have the same issue?
