Yes - see http://mercurial.selenic.com/wiki/Subrepository#Caveats . You 
might also be able to find this or something similar in the bug tracker.

Subrepos might be a pain, but it is not an itch people like to scratch 
in their spare time. So I guess the trick is that the corporations that 
use them should sponsor the features they need. See 
http://mercurial.selenic.com/wiki/Support .

The challenge will not be to solve the problem in a way that works you, 
but it will be hard to solve it in a way that meets the quality 
requirements of the Mercurial project.
