Crash with FrameList

[Birunthan Mohanathas]

I'm trying to extract the ID3v2 album artwork using TagLib (1.7) on Visual Studio 2010. Have been trying to get this to work for several hours now, but with no avail. The application always crashes due to the FrameList declaration. I've attached the problematic part of the code below.

---- code ----
	TagLib::FileRef ref(filename.c_str());

	if (ref.isNull() || !ref.file())
		return;

	TagLib::MPEG::File* file = dynamic_cast<TagLib::MPEG::File*>(ref.file());
	if (file && file->ID3v2Tag())
	{
		// Crash here
		TagLib::ID3v2::FrameList apic_frames = file->ID3v2Tag()->frameListMap()["APIC"];

		if (apic_frames.isEmpty())
			return;
	}
---- end code ----

>	NowPlaying.dll!std::list<TagLib::ID3v2::Frame *,std::allocator<TagLib::ID3v2::Frame *> >::_Insert(std::_List_const_iterator<std::_List_val<TagLib::ID3v2::Frame *,std::allocator<TagLib::ID3v2::Frame *> > > _Where, TagLib::ID3v2::Frame * const & _Val)  Line 975 + 0x3 bytes	C++

I've been able to use other TagLib methods (e.g. reading ID3v2 tags from files), but can't get the above code to work no matter what. I've tested with multiple MP3 files with valid ID3v2 tags/artwork.

Any idea?
