Assertion fail on TortoiseSVN Update

Hi, I'm Leonardo and I'm a svn and TortoiseSVN user.
 
Yesterday, I was working with TortoiseSVN, deleting a subfolder and when
I try to update the parent folder, the attached bug alert shown .
Previously, the delete of the subfolder operation stop with errors and I
should do it again (with success).
Next, on the update, this bug alert shown.
 
If you think that is a real bug, I'll write a complete bug report and
send it to dev mailing list.
 
Thanks,
Leonardo.
