KDE uses some pre-linking techniques to reduce startup time for applications; I'm not sure what the current version of the code does exactly, but it wouldn't surprise me if it involves PIE executables, which were known to have problems with our null-mapping prevention until recent bug fixes to rtld. If the problem goes away with an upgrade to a new userspace/kernel, I wouldn't worry too much about it. We added the null-mapping prevention a few weeks ago, and later discovered it interacted badly with bugs in our handling of PIE in- kernel and in rtld. Most likely (if the problem goes away with an upgrade), you just ended up with a bad combination of the two that was resolved.
