nspluginwrapper, Flash 10 and flashblock 1.5.7: very unstable

I'm using Flash 10 and nspluginwrapper 1.1.4 and Firefox 3.0.3 on
Mandriva 2009.0 x86_64. nspluginwrapper (different previous versions up
to the current 1.1.4) and Flash 10, have never worked stable for me.
Different things I'm seeing:
- npviewer.bin starts using 100% of cpu time, blocking my web browser
while this happens. strace and ltrace don't give any information about
what it's doing when this happens, but I could grab a backtrace with
gdb:
$ strace -p 4501
Process 4501 attached - interrupt to quit
^C
Process 4501 detached
$ ltrace -p 4501
--- SIGSTOP (Stopped (signal)) ---
--- SIGSTOP (Stopped (signal)) ---
--- SIGSTOP (Stopped (signal)) ---
$ gdb -p 4501

- A flash movie disappears as soon as another Flash movie on the same
page loads
- bug-buddy comes up and complains of a crash in npviewer.bin
- The whole web browser just crashes
What is probably a bit less common to my setup, is that I'm using the
flashblock 1.5.7 extension in Firefox, so maybe that is what triggers my
problems.
Also what I just saw when running Firefox in a console and opening a
movie on youtube (the movie played fine in spite of this error though):
*** glibc detected *** /usr/lib/nspluginwrapper/i386/linux/npviewer.bin:
double free or corruption (!prev): 0x093a5c00 *** (the movie played fine
in spite of this error though)
