[Bug 703301] [NEW] npviewer.bin uses too much cpu

[Chrescht]

Public bug reported:

Binary package hint: nspluginwrapper

When browsing some web-pages with flash the npviewer.bin process is using way too much cpu and memory.
top shows this:
7195 user     20   0  167m  74m  15m R   54  7.5   5:08.64 npviewer.bin                                                       
54% CPU on a Pentium D 3.4GHz is a lot, and so is 7.5% of 1Gb of RAM.
A sample page is this one: http://cgi.ebay.de/NOTEBOOK-IBM-THINKPAD-R60-CENTRINO-DUO-T5600-2x1-83GHz-/130475663503?pt=DE_Technik_Computer_Peripherieger%C3%A4te_Notebooks&hash=item1e60f4a08f

Output of ps ax| grep npviewer:
7195 ?        Rl     4:56 /usr/lib/nspluginwrapper/i386/linux/npviewer.bin --plugin /usr/lib/flashplugin-installer/libflashplayer.so --connection /org/wrapper/NSPlugins/libflashplayer.so/7162-1

Moreover I have found this segfault in syslog:
Jan 14 16:31:49 celsius kernel: [ 3080.799775] npviewer.bin[5073]: segfault at f3c9404c ip 00000000f61c2ee7 sp 00000000fff26190 error 4 in libflashplayer.so[f5e23000+b2e000]

cheers.
