Apps crash during screen setup change

[Thomas TEMPE]

gnome-settings-daemon crashed with SIGSEGV in g_simple_async_result_complete()

I was in single-monitor setup. I switched to dual-monitor through the display parameters dialog box, and validated.
As I was unsatisfied with the results, I canceled the change, and returned to the initial single-monitor setup.
The crash may be due to any of the two monitor setup changes.

I have encountered multiple application crashes, including LibreOffice Writer, while changing monitor setups since installing 11.10 beta. Every time, multiple windows are open, and one of them may crash.

I have a 13' laptop display and a larger external display, used side-by-side ; so any monitor setup change involves resizing of the desktop.

After further tests, I confirm that a freshly-opened LibreOffice Writer or Calc crashes systematically and immediately when changing screen resolution (single-monitor setup), whether it open over part of the screen, maximized, minimized, put on a different virtual desktop, and whether the screen resolution is increased or decreased.

The default terminal emulator, Chromium, Gnome file manager, Thunderbird, monitor setup app, xeyes, glxgear don´t seem to be affected.
