[Xcb] [BUG] iceweasel (debian's firefox) hungs on shutdown in libxcb1

[RALOVICH, Kristóf]

Hi,

this is reproducible and happened prior iceweasel 3.5 too. Although
this is the first time I cared to looking into it. See the backtraces
with package versions below.

I am willing to help on solving this, but please help!

For which package should I report this?

Thanks,
Kristof
