BankID on Ubuntu causes Firefox to freeze

I just installed Swedish BankID on Ubuntu 10.04, after that everey time I start firefox it freezes.
After a quick trip on google i found the sulotion in this thread.
All you need to do is to remove the libP11.so library in /usr/local/lib/personal/ aswell as installing the package libp11-1.

rm /usr/local/lib/personal/libP11.so
apt-get install libp11-1

After that it should work.
