with Linux 2.6.22, glibc 2.6, gcc 4.2.0, Qt 4.3.0, today's QtLauncher crashes when opening any web page (e.g. http://www.arklinux.org/). gdb backtrace: #0 0xb688e5c4 in QAbstractSocket::state () from /usr/lib/qt4/lib/libQtNetwork.so.4 #1 0xb68ae13d in ??

Same in today's svn -- the backtrace is less readable than before though: *** glibc detected *** /usr/src/ark/BUILD/WebKit/WebKitBuild/Release/WebKitQt/QtLauncher/QtLauncher: munmap_chunk(): invalid pointer: 0x08199b60 *** Program received signal SIGABRT, Aborted. 0xffffe410 in ??
