Curious, jprefs.js doesn't exists for K-Meleon
I suppose these files are under profile folder.
Create a new profile, as it seems that the last version has been installed over a previous one.
A bug I found (in setup?) that some files weren't deleted under chrome, and can be a problem for an upgrade from 1.0.2 to 1.1.5
