completion not inserting matches

[Thorsten Kampe <thorsten@thorstenkampe.de>]

I have the following directories in /usr/src:

linux@
linux-2.4.20-wolk4.9s-r6/
linux-2.4.20-wolk4.11s-r3/
linux-2.4.25-gentoo-r2/
linux-2.4.25_pre7-gss-r3/
linux-2.6.5-gentoo-r1/

Now I am in /usr/src and want to change to "linux-2.4.20-wolk4.11s-r3"
by typing

,---
| root@wolfbrand# cd r3<TAB>
| root@wolfbrand# cd linux-2.4.2--<TAB>-sr3
|                                ^ Cursor jumps to this point
| local directory
| linux-2.4.20-wolk4.11s-r3/  linux-2.4.25_pre7-gss-r3/
| root@wolfbrand# cd linux-2.4.2---sr3
|                                     ^ Cursor jumps to the end
| No match for: `local directory', `directory in cdpath', `user', `named directory', or `corrections'
`---

So the Completion System is correctly showing the possible two matches
on the first <TAB>, but doesn't doesn't insert them at the second
<TAB> and instead tells me now that there are /no matches/!

These are my completion settings: [1] and [2]. One "culprit" is

# case-insensitive and partial-word then substring
zstyle ':completion:*' matcher-list 'm:{a-zA-Z}={A-Za-z} m:[-._]=[-._] r:|[-./_]=** r:|=*' '+l:|=*'

and more precisely the "partial word" completion "r:|[-./_]=** r:|=*"
(which is directly taken from the user's guide).

So what am I doing wrong? Am I trying "to complete too much"?
