Hi , i shortly tested this with android sdk jelly bean 4.1.1 and "my
setup" dovecot 2.1.10 with included orginal android mail app in imap mode,
,leaving IMAP prefix blank, everything works as expected, no double
shown inbox, namespace problems etc
so you might have to fit your namespace setup.
Also you might follow allready given advice from here.

Anyway , i understand you using "stock client"
but you have to understand that the producers of mail clients
optimize their stuff fitting best in their own server structure
making money with it, therefor their motivation coding better imap code
is not very high, same case is for outlook and microsoft
however, i would say, fixing bugs is on the google site here, looks like
there is patch
at
http://code.google.com/p/android/issues/detail?id=1811
and the issue seems long known

i dont see any hard relation to dovecot in this case
meanwhile using k9mail seems the best way to workaround
there are lots of other bugs around android versions
over the years i dont expect google to fix them
