ajax: Somehow the crash sounds familar but I can't remember where I have seen
this before... is it possible that this is a DUPlicate ?
Comment 2 Adam Jackson 2005-04-17 17:16:06 UTC
if it's a duplicate, then the original needs to be reopened, because this
happens with HEAD (checked out about 90 minutes ago, freshly built).
Comment 3 Adam Jackson 2005-08-01 09:22:38 UTC
stuart anderson closed a different bug (setting Xvfb back to 8bpp default and
disabling 12 and 30 bit visuals) and now this no longer happens.  i should mark
this a dupe but i can't find the bug number offhand.
