Re: Mime type woes in beagle

[Michael Levy <mlevy wardium homeip net>]

I really appreciate the initial response, and this more detailed follow-up!

I copied your suggestion into test.cs, but I am afraid that I still get the
strange behaviour... I've attached a copy of test.cs just to make sure that I
haven't made another glaring silly...It still looks like memory corruption as
somethimes I enter the "loop" I described, others I get non-sensical
mime types (potentially non-printable characters) and other times I get a mime
type "g_free". I understand that there is a marshalling problem, but I'm afraid
I don't yet know what to do. I remain open to any and all suggestions ;)

In case it's important:
$ rpm -q gtk-sharp
gtk-sharp-0.93-1.ximian.6.0
I'm using Mono Beta 2

Thanks again,
Mike
