loop of rikaikun after a while

I start my browser and activate rikaikun right from the beginning. 
It works great for some hours.
Then, rikaikun does not display anything when mouse hovering on japanese be 
it on already opened tabs or new tabs.
If I look at my task manager I see that a google chrome thread is consuming 
all the CPU allocated to the thread. Since I have a core2duo it's not 
really a problem as it consumes only one core and I don't feel it.
If I kill the process and go back to google chrome it tells me that 
rikaikun crashed and propose a button to restart it.
After restarting it, it works again for a few hours.

I'm using chrome 4.1.249.1045 unknown (42898) and rikaikun 0.8 on vista.
I also use the extensions:
Chrome Stylist - バージョン: 2.0.2
Evernote ウェブクリッパー - バージョン: 3.0.8.320
Japanese Word of the Day - バージョン: 1.22
AdBlock - バージョン: 1.4.12
I have gmail and facebook always opened and also a tab with kanjibox (a 
facebook application to learn kanji). Then, the usual random surf.
I could not really pin point a scenario which would make this behaviour 
happen so far.
