Rygel/GUPnP licensing

[Jens Georg <mail jensge org>]

Hi,

having dug through the variants of (L)GPL license texts lately, I 
noticed that we apparenly have put Rygel and GUPnP under a weird mixure 
of LGPL v2 versions. The text and version comes from the "old" Library 
GPL 2, but as a license name we use "Lesser GPL" in the headers but 
Library GPL in the COPYING file.

Does anyone know whether I can just do a "soft" relicensing to "proper" 
LGPLv2.1+ by myself (the license says version 2 or later) to clean this 
up or whether I need to involve all contributing parties (oh dear)?

Thanks.
