Description

I had qtbase 5.1.1 installed and working, then upgraded libxcb from 1.9.1 to 1.9.3. This results in an segmentation fault with every qt5 application in /usr/lib64/qt5/plugins/platforms/libqxcb.so. I am not using Arch Linux, but the same issue was reported in their forum: https://bbs.archlinux.org/viewtopic.php?id=172746

Trying to recompile qtbase 5.1.1 using xcb 1.9.3 results in the following error:

/var/tmp/paludis/build/x11-libs-qtbase-5.1.1/work/qtbase-opensource-src-5.1.1/src/plugins/platforms/xcb/qxcbconnection.cpp: In static member function 'static bool QXcbConnection::xi2PrepareXIGenericDeviceEvent(xcb_ge_event_t*, int)':
