Backtrace of all threads (with debug info)

Seems different from the previous bug that occured when there was animation in the taskbar, since in this case there is no animation in the task bar (at least visibly). It happens about every hour or so and does not go away or change from its full cpu utilization until plasmashell is killed.

Backtrace of all threads is attached.

That shows all threads idling.

What would be the best way to get better information? I am greatly affected by this bug and so if there is something I can do to help assist in it being fixed I will do anything I can. Thank you.

Can you build your own Qt and apply patches to it?

Yes. I have a Gentoo based system so I could compile it with patches.

Let me know of what to patch and how to collect some information and I will rebuild and get you that information. Thanks!

Four of those threads are not idling, they're currently in baloo, looking for matches in lmdb.
