Version: (using KDE KDE 3.1.1) Installed from: Debian stable Packages When using kedit, kwrite, kate and clicking on the File->Print option or even browsing kcontrol printers section and clicking on one of the printers... within about 2 seconds the application crashes with a SIGSEGV signal 11. So basically, I can't print... but I can with qtcups and open office. I am running Debian stable with KDE 3.1.1 from the kde apt source. deb http://download.kde.org/stable/3.1.1/Debian stable main Here is the kcontrol backtrace: (no debugging symbols found)...(no debugging symbols found)...

Sorry to have been out of the loop. I think we either need a backtrace with debugging enabled and no optimisation, or be able to reproduce this. According to both backtraces, frame #6 is KExtendedSocket::KExtendedSocket, which is: // default constructor KExtendedSocket::KExtendedSocket() : sockfd(-1), d(new KExtendedSocketPrivate) { } That means that either some kind of inlined function is causing the crash, or that a parent constructor is or that KExtendedSocket's constructor is getting the blame without cause. Anyway, I can't tell. And decodePropertyRequestInternal in kdelibs/kdecore/kdcoppropertyproxy.cpp doesn't "mess" with pointers, so the only possible cause is a NULL parameter being passed down to it, by some other function that is missing from the backtrace.
