aptitude update crashes

["Hans-J. Ullrich" <hans.ullrich@loop.de>]

Hi all, 

when I try to get an update, I get the following error message:

Get:10 ftp://ftp.de.debian.org testing/contrib 2009-11-04-0016.39.pdiff 
[62.0kB]
Get:11 ftp://ftp.de.debian.org testing/non-free 2009-11-04-0016.39.pdiff 
[124kB]
E: Method rred has died unexpectedly!
E: Sub-process rred received a segmentation fault.

Seems, the cache-limit is set too low, or the packagefile is too big.

My cachelimit is set to

APT::Cache-Limit "100000000";

which should be enough, shouldn't it? I tried to increase it, but it had no 
effect. Maybe there is something wrong in the repository?

Best regards

Hans
