Looks like this was caused by the QML cache not having been cleared.
This normally happens during image upgrades, but since the Qt 5.4.1
upgrade is just done via apt-get this doesn't happen. The crashes stop
as soon as you delete ~/.cache/QML/Apps/maliit-server (or alternatively
if you delete this before restarting after the upgrade the crash never
happens). For completeness you probably actually want to delete the
whole ~/.cache/QML/Apps directory when testing this silo or you might
hit similar problems in other apps.

Title:
  A maliit-framework segfault with Qt 5.4.1

Status in maliit-framework package in Ubuntu:
  New

Bug description:
  Crashing at QV4::ExecutionContext::setProperty()

  See https://wiki.ubuntu.com/Touch/QtTesting for information on how to
  upgrade to silo 012 with Qt 5.4.1.

  All necessary Qt private headers users _should_ be rebuilt, per the
  latest knowledge. However, compared to 5.3.2 -> 5.4.0 transition, the
  following packages were found not to depend on qtbase-abi-5-4-0 /
  qtdeclarative-abi-5-4-0 so not rebuilt this time: oxide-qt qtubuntu-
  sensors qtvideo-node webbrowser-app ubuntu-html5-theme ubuntu-system-
  settings-online-accounts (some are recent known dropouts, some may
  have been without private symbol usage also during 5.3.0 -> 5.3.2
  transition). If in doubt, https://launchpad.net/~canonical-
  qt5-edgers/+archive/qt5-beta2/+packages has rebuilds of a lot of
  packages for the new testing reasons (unit tests get run etc).
