I've updated my system some days ago, and virt-manager appears to be broken. After short investigation, I found that gdk-pixbuf is the culprit: it should have something like /etc/gtk-2.0/x86_64-pc-linux-gnu/gdk-pixbuf.loaders generated, but it hasn't. Instead, after ebuild it says: ... --- replaced dir /usr >>> Regenerating /etc/ld.so.cache... >>> Original instance of package unmerged safely. /var/tmp/portage/x11-libs/gdk-pixbuf-2.24.0-r1/temp/environment: line 2761: 20046 Segmentation fault gdk-pixbuf-query-loaders > "${tmp_file}" * Cannot update loaders.cache, gdk-pixbuf-query-loaders failed to run >>> x11-libs/gdk-pixbuf-2.24.0-r1 merged. >>> Regenerating /etc/ld.so.cache...

I've searched some before opening a new bug, and decided that other (similar) bugs actually aren't as similar as they appear. These are found: 387083 and 395103 - they all claim some other problem, probably with coreutils or revdep-rebuild was not done. In my case, I have coreutils-8.7 and done all provisions from elog/summary.log, including all revdep-rebuilds.
Please re-emerge dev-libs/glib and x11-libs/gdk-pixbuf with "-ggdb" in CFLAGS and "splitdebug" in FEATURES, and get attach a gdb backtrace of the gdk-pixbuf-query-loaders segfault (see http://www.gentoo.org/proj/en/qa/backtraces.xml for how to do it).
I tried to create a backtrace, but it looks strange: #0 0x00007ffff2c89415 in QVariantAnimation::registerInterpolator(QVariant (*)(void const*, void const*, double), int) () from /usr/lib64/qt4/libQtCore.so.4 #1 0x00007ffff3278f9b in ?? () from /usr/lib64/qt4/libQtGui.so.4 #2 0x00007ffff7320995 in __cxa_finalize () from /lib64/libc.so.6 #3 0x00007ffff326ea16 in ?? () from /usr/lib64/qt4/libQtGui.so.4 #4 0x00007fffffffd5c8 in ?? () #5 0x0000000000000000 in ?? () I don't understand how it can depend on Qt. What shouild I do next?
Try re-emerging x11-libs/cairo with USE=-qt4
Okay, I remerged my system before Dec 28, when new version of Qt (4.7.4) was released. So I updated Qt (x11-libs/cairo actially wasn't rebuilt), and everything works now. So that was probably some bug in the Qt. Thank you for the help.
