Version: 1.1 (using KDE 4.1.3) OS: Linux Installed from: Ubuntu Packages I worked in Gnome 2.24.1 Dolphin has crashed during creation of the new association of *.aspx to be opend by kate. I made right click on *.aspx file -> Open with -> I typed kate, then I checked "Remember application association for this type of file" after that, as usually, a small window appeared showing something like "Changing system settings" I switch to different application to do something. The Dolphin was hanged when I switched back. The konsole window was opened in Dolphin during that. There is a crash report: Application: Dolphin (dolphin), signal SIGABRT (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) [Thread debugging using libthread_db enabled] [New Thread 0xb5f5c6c0 (LWP 8668)] [New Thread 0xb3cd1b90 (LWP 9392)] (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) [KCrash handler] #6 0xb8081430 in __kernel_vsyscall () #7 0xb67ea880 in raise () from /lib/tls/i686/cmov/libc.so.6 #8 0xb67ec248 in abort () from /lib/tls/i686/cmov/libc.so.6 #9 0xb75ca795 in qt_message_output () from /usr/lib/libQtCore.so.4 #10 0xb75ca872 in qFatal () from /usr/lib/libQtCore.so.4 #11 0xb6593a32 in Solid::Device::listFromQuery () from /usr/lib/libsolid.so.4 #12 0xb6593c8b in Solid::Device::listFromQuery () from /usr/lib/libsolid.so.4 #13 0xb7e5e140 in KMountPoint::Private::finalizePossibleMountPoint () from /usr/lib/libkio.so.5 #14 0xb7e5e5ec in KMountPoint::possibleMountPoints () from /usr/lib/libkio.so.5 #15 0xb7e1e7c7 in ??

The backtrace looks related to the one in bug 173325
This does not look like a kdelibs bug. For sure, it is NOT a Solid bug. Looking at the backtrace the following happens: * KOpenWithDialog is accepted and calls hide() * Something in Qt fails to hide the widget, it runs through some widgetAt() and eventually causes an XIOError * that XIOError calls exit() * static globals are deleted there, including the Solid globals * Dolphin also seems to have some global exit() handler installed (not sure why), and calls into KIO during ~DolphinSettings * the Solid query from KIO now accesses an invalid Solid backend manager -> crash I am not sure why Qt would cause an XIOError, but that part of the backtrace should be send to Qt Software for inspection.
Some googling revealed ../src/xcb_lock.c:77: _XGetXCBBuffer: Assertion `((int) ((xcb_req) - (dpy->request)) >= 0)' failed. so it looks like Xlib bug https://bugs.freedesktop.org/show_bug.cgi?id=14211 https://bugs.launchpad.net/xorg-server/+bug/185311 suggests export LIBXCB_ALLOW_SLOPPY_LOCK=1 for a workaround.
