Thank you Ricardonato for your report,

the crash is reproducible with the latests upgrades:

hjmf@paleo:~$ dpkg -l | awk '/flashplugin|firefox / {print $2" "$3}'

I have seen this same problem while running a fresh Feisty under Xen via Xvnc. I saw almost the exact same gdb backtrace. On my system, the failure was being caused by a firefox seg fault due to insufficient free memory while viewing certain flash-based web pages (including the one listed above in this bug). Strace similarly reported the same mmap2 failure due to insufficient memory.

My Xen DomU was given 256M RAM and 768M swap but those fancy flash pages were able to eat that memory up in about 30 to 40 seconds and cause Firefox to crash. Guest kernel 2.6.18 (.29, I believe), Xen hypervisor 3.1.0, Xvnc 4.1.2 plus "mv /lib/tls /lib/tls.disabled".

For me, I was able to resolve the problem I was having by installing the (9.0.64) .so from flashplayer9_install_linux_100107.tar.gz into /usr/lib/mozilla/plugins (it also fixed a weird colour inversion problem I was seeing as well but that's another story entirely).

Anyway, hope this info is somehow helpful to others.

we never saw any dupe for this. and the bug is almost certainly in flash anyway.
