Description Stefano 2016-11-14 19:53:25 UTC 
During the thumbnail re-creation job launched from maintenance, if you navigate the album the thumbnails are not loaded, resulting in empty view (also if the album is not involved in the re-creation)
Comment 1 caulier.gilles 2016-11-14 21:33:20 UTC 
The thumbnails database is certainly locked while maintenance tool...

Comment 2 Stefano 2016-11-17 07:22:53 UTC 
Uhm, a background operation that makes the app unusable is a bit odd to me. Being the thumbs container a database, I don't see the point in locking it, it can be read and written at the same time by definition and a conflict on the same record can be handled by the maintenance job itself.
