This affects me too, and setting QT_ACCESSIBILITY to 0 also works around
the problem for me.

Status in “qt-at-spi” package in Ubuntu:

Bug description:
  === PROBLEM ===
  Lyx 2.0.2-1ubuntu2 in Precise crashes when clicking or manually selecting anything in an open/save file dialog. The error message reported on the command line follows:

  QSpiAccessible::accessibleEvent not handled:  "8006"  obj:  lyx::frontend::DragTabBar(0xa728798) ""
  QSpiAccessible::accessibleEvent not handled:  "8006"  obj:  QObject(0x0)  " invalid interface!"
  QSpiAccessible::accessibleEvent not handled:  "8006"  obj:  QObject(0x0)  " invalid interface!"
  QSpiAccessible::accessibleEvent not handled:  "8008"  obj:  QObject(0x0)  " invalid interface!"
  QSpiAccessible::accessibleEvent not handled:  "8006"  obj:  QObject(0x0)  " invalid interface!"
  QSpiAccessible::accessibleEvent not handled:  "8008"  obj:  QSidebar(0xa9d0cb8, name = "sidebar") "sidebar"
  FIXME: handle dialog start.
  Interface is not valid
  ASSERT failure in : "Got an update for an invalid inteface. Investigate this.", file atspiadaptor.cpp, line 888
  Aborted (core dumped)

  === WORKAROUND ===
  apt-get remove qt-at-spi
  (this removes accessibility support for Qt applications, i.e. screenreaders may no longer work)
