In fact there are two cases:
1) the cached thumbnail has been created with <4.4 (hence no version): then the software string will just read "KDE Thumbnail Generator"; in this case the version is assumed to be <0;
2) the cached thumbnail has been created with >=4.4 and the thumbnailer has no version: then the software string will read "KDE Thumbnail Generator <pluginName> (v)", hence it is assumed to be 0. 

So you are perfectly right in case 2, which I forgot to consider. 
I will add a check for the property when writing the metadata; if the property.isEmpty() then the software string will read "KDE Thumbnail Generator <pluginName>", so that it will again be considered as <0.
