You should not create widgets from threads other than the main thread. To overcome this problem I use idle time processing callback (using g_idle_add() method). Basically, you have to create some idle time requests queue, that will create and display windows/messages etc. Then you can create the request from your thread (and optionally block until some mutex signals that the message box you wanted to be shown was closed).
For the details, you can download Atol source code (http://atol.sourceforge.net/) and see files ThreadSafeGui and ThreadSaveMsgs.
