MD5 hash is be5a2f9032f8fc8bccbbf5d96c5028f9.  Google has some matches
for that, suggesting that it's from Adobe.  I don't recall specifically
what I did the first time I tried to view a Flash widget on this machine.

But this doesn't address my actual bug report, which is concerned with how
Iceweasel behaves when a prior process has got wedged.  Avoiding wedgement
would be nice, but it's inevitable that it will happen sometimes, and the
system has to cope with it.  I can get similarly-wrong, but not identical,
behaviour by SIGSTOPing a perfectly-working preexisting Iceweasel process.
(In this case the new process hangs, and does not produce the error
window, until the preexisting process is continued, then starts up OK.)
