Hello, I just posted a question about a problem I'm having, probably due to programmer error on my part, to the Qt programming list. The thread with the details is here: http://www.qtforum.org/thread.php?threadid=18973 It was suggested to me that I also post to this list. The details are in the forum thread, including a trivial program that demonstrates the segfault; I won't copy them here. The summary is that I'm trying to write a simple app that does drag-n-drop between two QListViews using Qt 3.3.6. The original app is in Ruby using Korundum, but converting the app to C++ produces the same result of a segfault at the point that Qt finishes processing the drop request. I guess that I'm not freeing some resource, but the one tutorial I can find on using drag-n-drop in Qt doesn't go into that much detail. Any help is appreciated. Thanks, in advance. -- [ signature omitted ]

For now I have no clue, I just get lots of these error messages before the crash: Xlib: extension "SHAPE" missing on display ":0.0". Xlib: extension "SHAPE" missing on display ":0.0". Do you see them as well? Indeed 'xdpyinfo' shows that there's no SHAPE extension, but I don't know to what extent this is related to the crash: $ xdpyinfo [...] number of extensions: 15 Composite DAMAGE GLX MIT-SHM NV-CONTROL NV-GLX RANDR RENDER SECURITY XC-APPGROUP XFIXES XFree86-Bigfont XInputExtension XKEYBOARD XTEST [...] $ -- [ signature omitted ]
