Is anyone else running Picasa under Lubuntu 11.10?

I decided to give the new Picasa 3.9 a test, so I installed it over
3.0. So I'm not sure if this problem is just with 3.9 or with Picasa
in general.

The problem is once you run Picasa you are not longer able to run
pcmanfm, not from a link or desktop icon (folder) or from the command
line.. nothing!

I use to use Picasa regularly in Ubuntu ( 3.8 ) and had never had
any trouble with it.. but since switching over to Lubuntu a couple
of months ago I had not used Picasa since.
