firefox crashed with SIGSEGV in __kernel_vsyscall()

[Peter]

Binary package hint: firefox-3.0

Crashed happened when selecting image to download through 'Set as Desktop Background'. The action did work, ie the downloaded image is the background, but at that point Firefox became unresponsive and crashed.
