Using QTcpSockt to check an IMAP server

[guilugi]

Hello there,

I have some troubles using QTcpSocket (Qt4)

My code does those simple steps :
- Connect to an IMAP server
- Login (with username / password pair)
- Look for new messages (if any)
- Logout

I checked the FortuneThreaded in the Qt4 doc, and tried to do something similar...
but it doesn't work that much : it seems I can only connect to server...
And the program seems to close unexpectedly, even if I put some sleep events...

I joined my two files in attachment !

Thanks in advance for any help,

Guilugi.

PS : I had some similar code made with Qt3, and it works perfectly, I'm sure that's a silly mistake from me
