Re: [gmime-devel] using gmime in a multithreaded application

[Dan Streit <danws6 gmail com>]

Thanks Jeff,

That has fixed the segaults but now I've run into another interesting problem. When sending mail through with a bogus from header it seems the library never comes back, for example: 

From: =?ISO-8859-1?Q?LibertyMedical=AE?= <redacted redacted com>

Looking with the debugger:

Do I need to do something special to handle cases like this?

Thanks again,
Dan

You probably need to initialize glib with thread support so that it
knows to lock inside it's memory allocator.

g_thread_init (NULL); ought to do it
