Description Scott Kitterman 2010-06-21 15:28:41 UTC
Application: knetworkmanager (v0.9)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I was connected to one wifi network and manually switched to another when the crash happened.  I assume the crash was late in the connection process, since the connection succeeded.

 -- Backtrace:
Application: KNetworkManager (knetworkmanager), signal: Segmentation fault

not an oxygen bug as far as I know.
It has been reported elsewhere to occur also with other style (though I could not find again which one any morE).

I believe its a KNM bug, due to dangling pointers to previously deleted action (hence the crash in QAction::isSeparator).
whoever access the action first (here oxygen +style+) makes the application crash.

There are many (similar) bugs reported on this. I mark this one duplicate of one of these ...
