How have you checked the IGC file for gaps? By loading it into SeeYou?
SeeYou will automatically skip over an out of order fix when
displaying a flight. My guess is if you checked the IGC file in detail
there is an out of order record.

A regular fix will look like this:
B1929283318443N11641991WA0121001246000000000000

A bad fix will probably look like this:
B1929323318500N11642046WV0121701255000000000000
Note the 'V' after the 'W' , instead of an 'A'.

After uploading my latest flight to the OLC, the server told me that
the file was invalid due to a large time gap between GPS fixes. Both
my secure *.cai and *.igc files show no such gap; it only appears on
the OLC trace. I've sent an e-mail to the OLC to see what they think,
but I'm curious to see if anybody else has had this problem, and what
they did to fix it. Thanks in advance!
