Bug#549313: metacity: assertion failure trying to flash the frame of a frameless window

[Simon McVittie]

Package: metacity
Version: 1:2.28.0-1
Severity: normal

To reproduce this, for example:

* Configure GNOME to use a visual bell
* Install Sonata and configure it (in Preferences -> Behavior) to suppress the
  window frame
* in Sonata's Library tab, press backspace in an empty Search box; this would
  ordinarily beep, which is remapped to visual bell (flashing the title bar)

Expected:

* either nothing happens, or some other visual bell indicator is used

Actual:

* Metacity crashes and is restarted, with:
  metacity:ERROR:core/bell.c:211:bell_flash_window_frame: assertion failed: (window->frame != NULL)
