The answer to this bug is: please run revdep-rebuild. Of course libgphoto2 does have its own issues with libtool 2.2 (bug 212721) but till then I think the bug is invalid.
Right, I found this out after opening the bug. I merely opened it as I had seen a lot of other bugs related to libtool and thought this one was too. I've checked gvfs's code and nowhere does it use ltdl directly. So I guess this is moot. Thanks for the reminder.
