error with apt-get archive

[Lukas Ruf <ruf@rawip.org>]

Dear all,

on one of my boxes, I am not able to run an update.  The error is:

Hit http://www.netbeast.org unstable/main Packages

E: Problem with MergeList /var/lib/apt/lists/_var_cache_apt-build_repository_dists_apt-build_main_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.

I am running sid with apt-get 0.5.5.1 on an ia32 box.

Is there any way I can fix this problem?  Strange enough, on other
boxes there is no problem with sid.

TIA.

wbr,
Lukas
