Does it happen with all vobs or just one? Does changing the seek time
have any influence on it?
As a temporary workaround you can use -ss as an output option (move it
before the output filename), which will be slower (since avconv will
decode everything), but should work more reliably.
Also note that -t is strictly an output option, specifying it as an
input option has no effect (i hope to fix the options parser so it
prints an error in such a case soon).
