Unfortunately, there's currently no mechanism to allow a Wiretap module
for handling a particular file type to report such an error - and there's
no mechanism to have an "init" routine for the module, which is where the
file should be read in any case.

You'd have to wait for such a mechanism to be added.  They probably should
be added; Ethereal, Tethereal, etc. would call wtap_init(), or something
such as that, to initialize Wiretap, and it would either return TRUE if it
succeeded or FALSE if an error occurred.  If it failed, it'd also return a
string that Ethereal could put in a dialog box and Tethereal could print.
