media_thumbnail dimension mix

Hi
This confuses me a bit. The Media module create and define a image preset, media_thumbnail. It define 100x100px though I see you mention 180x180 in several comments around. 7.x-1.x uses 180x180 and 7.x-2.x changes this to 100x100. It also confuses me that media_update_7211() try to define 180x180 if the preset is missing. This will leave a 7.x-2.x installation with a 180x180 and that cannot be right?

Tested and verified on a clean minimal D7 installation.

Media 7.x-1.x clean install
