Due to the large amount of storage used by /var/tmp when building VirtualBox,
my installation has /var in a separate partition. When I try to install any
recent snapshot of TW, several packages fail to install with the reason
"Subprocess failed Error: RPM failed, Command was killed by signal 11". The
first 4 packages that have this error are breeze5-cursors, hicolor-icons-theme,
akonadi-mime, and kde-filesystem. After the last of these, I aborted the
installation.

Removing the mounting of my /var, installation was normal.
