Assignee:	Nathan Woodrow
Category:	Project Loading/Saving
Affected QGIS version:	master	Regression?:	No

Crashes QGIS or corrupts data:	Yes	Copied to github as #:	17035

Description

Version QGIS master version b7d7076

Issue : With an existing opened project, when you load a layer from the browser, then click on the Save button, QGIS crashes and corrupts the project file (project file size then : 0 ko). If the layer is loaded with the Add Vector layer menu, everything is ok

How to reproduce

open the attached project debug.qgs
open the attached shapefile with the classical "add vector layer" menu, the save --> Ok
open the attached shapefile with the browser panel Then save --> QGIS crashes
