I made a hackish patch for QProcess in Qt (usleep(1000) before fork()) which
seems to reduce likelihood of the failure to very rare again. Once a new
revision of qt4-x11 is uploaded to sid (soon I believe), KDE applications
should be able to build again (hopefully).
Obviously it would be better to get this bug fixed for real but at least now
the whole KDE stack won't be held by it while we wait.
