Rumpus FTP DoS vol. 2

If anyone remembers I posted a DoS Vulnerability description to BugTraq, and 
Rumpus Developers quickly repaired, it, but they missed a thing. When executing 
command mkdir A:A:A:A:A:A:A:A:A:A:A:A:A:A:A:A:A:A:A:A Rumpus quits, its not a 
system freeze, but FTP service will be denied. This is a stack overflow caused 
by recurising through the folder creation routine that happens when many layers 
of sub-folders are created at once. The Guys behind Rumpus(Maxum) is a really 
good team of developers... I mentioned the vulnerability and in hours there was 
a new, fixed version. So vulnerable versions are: 1.3.5 and earlier, 2.0dev3. 
Not vulnerable: 1.3.6(I guess it should be downloadable already) and later...
