you probably have a library conflict between libraries and pluggins (bite me once) you could try replace the liboxygen* in /usr/lib/kde4/plugins/styles/ by your home made (likely: ~/kde/install/lib/plugins, or smthing similar) or manually edit $HOME/.config/Trolltech.conf, (find "libraryPath" and put the correct kde path there, or keep empty) obviously cannot reproduce here.
yes that solves it! thanks :)

Hello! Help please. I dont know is the problem only for me like this or no - i only have the problem when i select PROJECT NEON at startup menu, if i choose KDE it works flawlessly. Till two days before it didnt have this problem. I tried opening $HOME/.config/Trolltech.conf, and find expression "libraryPath", but there was none... also ~/kde/install/lib/plugins home/(myname)/kde/... doesnt exist home/(myname)/.kde/... exists but no subfolder "install" exists /kde/... doesnt exist /.kde/... doesnt exist im a complete noob... can u help me understanding which folder i should look into and what exactly i should replace... i really dont want to make things any worse... and id love to continue use of project neon, so i can contribute to the better development of kde & kubuntu. thank you! symon
@Simon, I have no idea about what can be wrong, nor am I familiar with project neon. You'd better ask on neon's forum, you'd get better assistance here, from others which use the same setup as yours. From what I can tell, there is no actual bug involved in oxygen (nor kde) code base itself (I'm running home-build kde from master here, and everything is nice and smooth). Sorry. Can't help
For Project Neon you have to add [qt] 4.7\libraryPath=/opt/project-neon/lib/kde4/plugins into ~/.project-neon-kde/config/Trolltech.conf, then it will work.
Hello! Now after i did something (in system settings under login screen i have chosen to disable themed mode and use the simple mode), after reboot, it said in this enivornment kubuntu wont load in project neon, just in normal KDE workspace and in the options of the login menu project neon doesnt appear anymore. :( The problem is now this... when i load kubuntu (the kde workspace), i have the same problem with kwin (it says it crashed a lot and doesnt enable it). can you please tell me in which trolltech.conf i have to write and how should the line look like? (like it is written for project neon in the previous post?) i tried to use the information from all previous posts but i think i made it even worse than before, coz it doesnt say exactly what i have to put...and where - like it says for project neon... thank you! Symon
i would also like to add one thing about this bug. Maybe it happens only in project neon - i dont know, BUT, ...after updating this is the second time it happened, that the path to the correct libraries became not correct by itself - i mean, i didnt change it. So it has to do with something with the installation/updating process. Somewhere during that, the path in trolltech.conf becames wrong. what i want to say is... like this to repair it by hand doesnt fix the bug, maybe it should be fixed with change to some installation/update package, who specify the path to that folder ... i dont know... i just suggest... thank you! Simon :)
@simon well, since this is an installation problem, you will likely not get much help here, unfortunately. Project neon's forums is the right place. As for the suggestion to fix in the install process, same thing. Now this is not specific to neon. This is specific to everyone installing kde in a non standard directory. But the issue is with Qt, not oxygen, and you'll have the same issue every time you re-install Qt, even without changing kde install. so no, kde can't (and should not) provide a package to "fix" the Qt install.
I'm adding this for a future reference. PLEASE do not add anything more about PROJECT NEON, the problem that was there is already solved. Adding more Neon related comments just makes this bug unnecessarily long. Noone is going to read it when it's too long. Use Neon forums or #project-neon at freenode. @Simon - by changing your kdm options from Project Neon, you pretty much messed up your system :) It overwrites /etc/kde4/kdmrc config file with different paths, thus pretty much screwing everything. You no longer see 'Project Neon' in kdm because it became 'KDE Workspace' and you no longer have access to the stable distro KDE. However try solving this elsewhere please. As for the trolltech.conf - changing that config was recently added to package scripts, from what I understood, that found a more sophisticated way how to do that correctly (read change it elsewhere). I'm on Project Neon myself and everything works as expected, it's most likely your config problem, sorry.
