Comment 131 for bug 220628

I'm surprised that I'm only the 6th person to tick the "me too".
I'm really pested with exactly the same problem.
Every half an hour or so, Firefox disappears when active with many windows and tabs.
I also experienced Thunderbird disappearing, but far less often.
Even Pidgin disappeared a couple of times.
At first I thought it was IP related.
Until I saw that same X BadIDChoice message and I came here.
Should I also mention that Gnome (GDM I suppose) most often cannot switch to another session because of an X failure? It rarely fails when a second attempt is made.
I didn't check any message except in the Firefox case, though.

Ubuntu 8.10 (Gnome). Firefox 3.0.15. libxcb1 is 1.1-1.1, which seems to be what matters.

What should I do to get rid of such a nasty problem?
Shouldn't bug summaries explain the procedure to follow in terms that can be understood by everybody?

How do I get to using 1.1-1ubuntu1 instead if it's true there's no problem with it?

If the importance is "unknown", I can help: it's high for active people using the Web a lot.

Thanks.
