Hi,
When i clic , import, view,... or any action on one of my epub , calibre freeze during 5mns and return without any error.
I found inside this epub a strange content.opf (or metadata.opf), after i deleted "description", all return ok
The discription it's also loading inside the database, so even if i remove the file and check the library, no error are decteted but the probleme alway exist

So why a corrupt description can hang calibre like this ?
PS : i use the last calibre 64bits version

Here the file attachement ( i can also if you want give the epub)
