Bug#438815: Segfault when dlclose()ing libopenh323

[Faidon Liambotis]

severity 438815 important
thanks

[release team: the bug is about a segfault of users of libopenh323 that
happens when they dlclose() the library; see #48 for more.]

Since upstream is quite unresponsive generally and in this case they
haven't even looked at the bug, it has been workarounded by the only
package affected by this, asterisk.

Even though
a) I believe this is a serious issue,
b) it "affects other packages",
c) the workaround is ugly,
it is my opinion as the bug reporter and maintainer of both packages
that this isn't a release blocker and doesn't deserve to be marked as
"grave" anymore.

I'm Ccing the release team for their opinion since Marc was grumpy about
the relationship of severity and workarounds recently.

Thanks,
Faidon
