[Bug 195229] Re: emerald crashed with SIGSEGV in main_arena()

[Kees Cook]

** Description changed:

  Binary package hint: emerald
  
  I was scrolling through the xorg logfile using less in the gnome-
  terminal when emerald abruptly died (though I don't believe the two are
  related; emerald has died several times before with no apparent rhyme or
  reason; the only reason I hadn't reported the bug previously was because
  the debugging symbols for emerald were not complete so the backtrace was
  useless)
  
  I am using the 'Blueray' v0.3 theme. Modifications I've made via Emerald
  themer 0.5.2 are: change the window shadows to a more cyan-ish color,
  change the titlebar text font to 'Swift' 12 point (I am uncertain what
  package this font is part of if it is not part of a default
  installation). I believe emerald died unpredictably before these
  alterations and with other themes as well, however.
  
  Windows open at the time:
  Firefox 3b3, one gnome-terminal, evolution mail, pidgin
