i reported a bug in kontact 4.13.1 yesterday. they fixed it (almost immediately, which leads me to believe that i wasn’t the only one who had the problem, but i’m the one whose name ended up on top of the bug report) this morning, and, with the kubuntu-updates ppa (which i hadn’t installed, because of the fact that i didn’t know it existed) my installation of kontact 4.13.2 is working wonderfully, less than 24 hours after the bug was first reported.
given my experience as a software tester, i don’t have to wonder what the process would have been like for mac or windoesn’t, especially with as important a communication tool as kontact…
THIS is the reason i am a linux geek… 
according to this, the bug that i reported yesterday has been “RESOLVED FIXED” in Kontact 4.13.2…
i am running 4.13.1, so it should be an easy upgrade…
this guy recommends that i use PPA/Backports to install 4.13.2, but 4.13.2 is not a part of the current PPA/Backports repository, and there’s no telling when (or even if) it will be added…
in other words, they fixed the bug that i am experiencing, but i can’t get to the proper repository to install the fix because i choose not to run on “the bleeding edge” and like to keep my installation on the “Long Term Service” (LTS) version as long as possible.
ETA: i tried removing and reinstalling kontact 4.13.1… it didn’t help.
