This indeed is caused by having kde-style-polyester installed, NOT IN USE. I am using Oxygen and have been for a long time. Removing kde-style-polyester causes the problem to go away, re installing without touching System Settings causes the problem to immediately reappear. I am quit sure that I did not have this problem before. I wonder what upgrade caused kde-style-polyester to be installed. and have been for a lo9ng time
Thanks for the bug report! (In reply to comment #1) > This indeed is caused by having kde-style-polyester installed, NOT IN USE. I > am using Oxygen and have been for a long time. But the backtrace clearly shows that it crashes in Polyester code. I think that Polyester does not use bugs.kde.org for tracking bugs, so I cannot reassign the report. I don't know why the Polyester style is used even if you don't enable it explicitly. Have you tried to open System Settings and switch to another style explicitly, and then back to Oxygen? Does the problem persist then? If the Polyester style was installed via some distro upgrade, maybe the distro configured it to be the default. Either way, this is clearly not a Dolphin bug, and my knowledge of styles is rather limited, so I can't provide any other suggestions what to try. Sorry about that.
Polyester most certainly crashes because it assumes a widget is passed to the drawControl() call when rendering the header, but it is documented that a null pointer is safe to use. A similar bug has already been reported to http://kde-look.org/content/show.php?content=27968 over a year ago (see latest comment), so I doubt the style is still maintained. I always hated that kde-look.org is no public repo, where others could commit improvements, but if you point me to a public repo for Polyester, I can commit a fix.

I had that problem some time ago. Right now I am running Kubuntu 14.04 and do not have the problem. The cause as I seem to remember was having Plymouth loaded. Plymouth is loaded on my system at the moment. I see that there is an app called plymouth-disabler. Its stated purpose is "This disables plymouth from running by installing .override files for each of the plymouth jobs. Its sole purpose is to work around bug 1235231." This app is not running on my machine. Remember my mind fools me at times but check on that bug number and see if it addresses your problem. Oh, what version are you running.

I am wrong! Ignore that previous reply. kde-style-polyester is the culprit. Make sure that you do not have it loaded.
