As far as I can see there are 3 ways to fix this.
1) Completely disable mipmapping for compressed textures with 0 custom mips. However without any mips, the terrain looks very grainy from far away.
2) If a compressed texture contains no mipmaps, and we don't have RSC_AUTOMIP, uncompress the texture before loading it so that mips can be generated in software. Here is the change: http://pastebin.com/E9JvDWy7
3) Convert the compressed textures in the samples so that they contain mip maps, and declare compressed textures without mipmaps as unsupported.
In my opinion, option 2 is best. But it currently doesn't work very well due to a bug with DXT decompression. Opened a separate report: https://ogre3d.atlassian.net/browse/OGRE-268

Oh yeah, now I remember. That was the reason behind the GenerateMipmap change to begin with.
It's related to attempting to generate mipmaps with compressed textures.
Testing latest 1.9 branch, this is what the terrain sample currently looks like (endless world looks the same)
