Monster Chinese v5.1 + Qtek 9100 1.6.7.1 ROM = ERROR!

I dont know if anyone have similar combination (could be Qtek 9100 or Dopod 838 english)

Install Monster Chinese v5.1, then try the following:
1. Open contact application
2. Type search keyword (a few letters, make sure it has matches) in the quick search bar
then the application will quit automatically.

Its extremely annoying- I have reported to mactiontech but they NEVER answer question.

Any good clue?
