Description

When a layer is deleted, it remains in the project somehow and slows down loading. When I had 30 layers in a project and it was taking almost a minute to load, I tried copying the project then deleting half the layers from each. It took just as long for each to load after half the layers were deleted as before. When I recreated one project with only the desired layers, it reduced storage from 147 Kb to 111 Kb and loaded almost immediately.

What version are you using?

Would it be possible to attach the affected project files?

I can't reproduce it. I am using QGis master on Ubuntu 13.04

Duplicate of #7426, closing this because the other has sample data attached.

Please reopen this bug as issues still occur as previously reported (see also by my original bug report #7086).
I changed computer and QGIS version (now running QGIS Valmiera 2.2 on a Windows 8.1 64bits laptop) but still have the same problems described above.
In the project file I'm attaching, the project is made of only one point vector "cities", which displays without problems. However, many other "invisible" layers are present in the .qgs file and also listes by selecting Project/Project properties/Vector information from within QGIS.

PS
Deleting the "cities" layer results in QGIS crashing.

Can you reproduce the problem with a fresh project (ideally on 2.4 or master)?

PS: Deleting the "cities" layer results in QGIS crashing.

Might be #9779.

see attached images: opening the project in qgis 2.4 the layers are not "invisible", in fact qgis asks for them (including "cities" that you haven't attached here).

You just notice, because the layer data is not available. They are only in <projectlayers>, but not in the <legend> - so they wouldn't show, if the project was loaded flawlessly.

The question still is what removes a layer from the legend without removing it from projectlayers.
