Archive view shouldn't block UI while loading

[raphinesse]

When selecting an archive in the tree view just to delete it, it is opened and the ui blocks until it's contents are shown. Blocking is in the order of few seconds for a ~6MB tar.gz on an Athlon II X4 635.

Automatic opening is fine, but archive-view shouldn't block the UI while it's at it

What type of archive was it? A .zip, .tgz, something else?

[raphinesse]

I can't check it right now but I'm pretty sure that it was a `.tar.gz`.

When this will be fixed? it is opened 2.5 years and still happening with jar file.
