Bug description:
A memory leak in policykit causes memory exhaustion over time in
kdeinit4.
[Test Case]
1- check memory usage of kdeinit4 under htop (RES column)
2- ssh in
3- check to make sure it stays constant
[Regression Potential]
If the patch is incorrect, policykit could possibly crash.
Every time ssh login is made on ubuntu 14.04, kdeinit4 leaks 2-3 Mb (when kde is installed).
According to previous bug report in: https://bugs.kde.org/show_bug.cgi?id=271934
this is a bug in policykit-1 package, and it has been already fixed on upstream.
Update of policykit-1 should fix this problem on kubuntu 14.04 and Ubuntu 14.04 + Kde.
This bug is severe in some specific scenarios where ssh is often used.
In my case, I have a lot of scripts running processes every hour between ubuntu and kubuntu machines using passwordless ssh login. In few days kubuntu machines don't have free memory, due to the referred leak.
