Qt and XPCOM with eclipse

[Arifa]

Hi,

I have a problem

I call an XPCOM wrapper from XUL code .
The wrapper calls a Qt code.
I have built it in eclipse.

The flow is

Text entry writen in XUL -> XPCOM -> Qt

The declaration works fine but when we start working with the elements it crashes.

For eg:

QUrl url ; // works fine
url.setUrl ("afd"); // crashes

Could you please help me out.

Thanks
Regards
Arifa
