I think Frank is right that it must be something not working properly in 
the code that tries to construct the path to the individual files in the 
MITAB OGR driver.

Is there a way you could share a sample dataset to reproduce this? 
(Perhaps off-list) ... or even better, file a MITAB bug and attach the 
sample dataset to the bug:

I doubt that's the issue. Seamless table support was added in 2001 and 
the last serious fixes specific to seamless tables in MITAB were done in 
2004 (just a memory leak), so it would have to be a quite ancient 
version of OGR... so ancient that it might not work at all with a recent 
version of MapServer.
