The error isn't about krunner but about kdeinit5, which can't find the .so to 
dlopen.

I suggest debugging a bit in kinit.cpp, function launch(), to find out more, 
but it looks like this function is already getting a full path as input?

You could try adding a lookup in LD_LIBRARY_PATH in that code, to make it more 
flexible --- or in the calling code, if indeed the problem is before that.

Problem number 2: this kdeinit5 dlopen stuff is supposed to be optional, 
kdeinit should fallback to executing the binary, otherwise. I.e. this code is 
supposed to clear libpath and keep only execpath, and find it ("kwrite") in 
$PATH.

Happy debugging :-)
