Just had a slightly different kind of freeze, which didn't beachball but was even more annoying in that I could only get out of it by killing KDev.
It happened when I right-clicked on one of the .po files in the Audacity source project that I had open. As "luck" had it I was running kdevelop from inside lldb, so below is what I could get in terms of backtraces. They don't seem very helpful, but maybe they are for someone intimately familiar with the code.
I also had over 10 zombie clang processes all spawned by KDevelop.
