If OASVN is ordered to retrieve more revision logs than actually exist (default value: 50) the software is entering an endless loop.
Also please keep in mind, that normal humans start counting by 1 not zero
By testing your product with a newly created repository I tried to retrieve the last 5 revisions. Therefore I entered 5 which lead to previously described infinite loop. After requesting the last 4 revisions, all 5 existing ones where listed correctly.
