when using a long running yast ui written in python I observe the process size keeps increasing. Normally this is not problematic as yast UI clients are short lived. However in my case I am using a yast ui written in python that runs indefinitely on a low memory device (raspberry pi) and this becomes problematic.

This is a pretty specific and not normal use case so normal priority and no need for backporting imho

a valgrind trace as follows shows where the leak is occuring
