There isn't enough information to make progress here. Just clicking randomly in the library list didn't cause any problems for me. What exactly were you clicking on? How many times? What else what going on at the time? Did you get a failure report or crash ID?
Closing pending more information.
Nothing extracted yet.
When I was clicking the names in the list on the left of the client it caused a segfault as you can see on the last line from the terminal output. This behavior is repeatable.
