Hi (again… sorry), It seems that tumblerd (the dbus service) is licensed under GPL and tumbler (the lib) under LGPL. But a few headers in tumbler/* contains the gpl comment, which would probably make libtumbler gpl instead of lgpl since they are apparently linked together: - tumbler/tumbler-provider-plugin.c - tumbler/tumbler-thumbnail-flavor.h - tumbler/tumbler-thumbnail-flavor.c - tumbler/tumbler-thumbnailer.c - tumbler/tumbler-cache-plugin.h - tumbler/tumbler-cache-plugin.c I think it is another occurrence of the "unfortunate copy/paste" curse. :) Thanks!
Yes, this is a copy and paste mistake. tumblerd is supposed to be GPL, the tumbler library is LGPL.
