homemade PyS60 extension can not run on the device

[Davidz_USTC]

Hello, everyone. The following link is my homemade PyS60 extention. It is a simple wrapper of Symbian's sms service:
http://home.ustc.edu.cn/~davy/smsmodule.zip

I made it based on the code here:
http://wiki.forum.nokia.com/index.php/SMS_Operations
and I added 3 functions to it: DeleteMessageL()、SaveMessageL()、ParseMessageL()

Currently, it runs well on the emulator. But when I compile it with GCCE and copy it to the phone, I can import it in the PyS60 shell. Then when I try to run any of the 3 functions, the PyS60 shell crashes....

I tried many ways to figure it out, but I always failed...

Now I have no idea with it since I can't find any detailed documents except the official PyS60 document '8.1 Extending PyS60'. So I came here for help.

Thanks! and sorry for my bad English...

Does it throw any panic? Any panic displayed?

Does it throw any panic? Any panic displayed?

No, the PyS60 shell just crashes when i try to use any of the 3 functions...

I uploaded the GCCE compiled pyd file here:

Thank you very much!
