dumpcreated but with errors

hi All,
I have created the dumpfile but it had reported some errors....

BUILDACTIONHIST:
   Attempt to add entry 'RAAAAAAA' with unknown version number (probably destroy
ed)
at vss2svn.pl line 1066
   Attempt to add entry 'QLAAAAAA' with unknown version number (probably destroy
ed)

   Attempt to add entry 'EGCAAAAA' with unknown version number (probably destroy
ed)
at vss2svn.pl line 1066
   Attempt to add entry 'FGCAAAAA' with unknown version number (probably destroy

What do these mean? and would there be any problems because of these ...? how to resolve them?
