Out of curiosity, which request events do you return NULL for?  Don't you
usually have to perform some action and call one of the supplied callback

That being said, it seems like this might be a bug in libpurple.  libpurple
should probably not call purple_request_close_with_handle or
purple_notify_close_with_handle if the handle is NULL.  Do you know the where
these calls are happening?  One way to determine the source is by setting
D_DEBUG=fatal_warnings when running your application.  That will cause glib to
assert() and crash when it encounters these errors.  From there you can use
gdb to get a backtrace and see the call stack.

I'm wondering if the calls are coming from purple_request_close_info() in
libpurple/request.c.  It seems like those should call purple_notify_close()
instead of purple_notify_close_with_handle().
