how to disable kde5filepick etc....

I recently noticed on my hp pavillion laptop (tumbleweed/KDE standard install) that the fan gets noisy very quickly, even though I was just reading the news on the internet. I checked what was going on and was surprised that the top command showed the following:

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND                                       
 2230 uli       20   0  458768  96568  81504 R 100.3 0.793  14:39.37 lo_kde5filepick                               
 2243 uli       20   0  458776  96608  81544 R 100.3 0.793  14:39.23 lo_kde5filepick                               
 2248 uli       20   0  458764  96276  81216 R 100.3 0.791  14:39.10 lo_kde5filepick

Why are there 3 differend processes of kde5filepick with 100% CPU?
I killed the 3 processes and was surprised that amarok then used nearly 50% CPU - that cannot be right either?

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND                                       
 2129 uli       20   0 1909908 142764  84088 R 48.50 1.172   6:22.57 amarok                                        
 1269 root      20   0  375456 101816  75472 S 0.997 0.836   0:25.32 X    

Something must be wrong in the set-up here? Any ideas?
Thank you

The file lo_kde5filepick belongs to libreoffice:

locate lo_kde5filepick

And I found that this problem is widespread and there are bug reports from Arch Linux ( and Debian ( but this problem was reported from other distros as well, e.g. Manjaro and Antergos. The strange thing is that I haven’t used libreoffice but I have this problem for 3 days already.

Just for the benefit of those reading this post. Upgrading tumleweed to version 20190108 included an upgrade of libreoffice to version and there the problem with this file lo_kde5filepick is gone. At least I on my computer I opened several libreoffice files and lo_kde5filepick didn’t appear in the top command any more.
