I don't like this potential crash when remove a layer used on the composer.
We also experience this kind of situation on qgis 2.0. In qgis 2.2 I lost of sight the question because our users knowing the problem paid attention to avoid to remove a layer. :) Now I like to try to replicate this problem. Just some information to understand your infrastructure: your crash happened using always the qgis64 from osgeo4w-64 or also sometime with osgeo4w-32 ? You use qgis 2.2 stable or dev ?
