you're missing the debugging symbols for oxygen (see /usr/lib/kde4/plugins/styles/oxygen.so), which I'd need for debugging. Could you install the debug packages for kde-workspace ? Also: does the crash occur every time ?
That oxygen.so is from my distribution ( kde-4.6.2 ), but i have a devel environment with master compiled. I don't know why it's picking up the wrong one. Anyway, feel free to close as invalid as this is probably the cause. I'll reopen if it still happens with oxygen.so from master.
Oh, yes, that it picks the wrong one is likely the cause, And I do know the reason why: Qt adds its own guess concerning your kde installation for pluggin path, disregarding your compiled version. You can change that by editing $HOME/.config/Trolltech.conf (look for library_path). That should fix it. (alternatively, make a backup copy of the old oxygen.so, and link the right one there instead). Closing, as requested ;)
