Bug#473182: kdebase: KDE applications waste minutes in launching

Package: kdebase
Version: 4:3.5.8.dfsg.1-7
Severity: important

Sometimes KDE turns into a state in which some KDE applications as like as D3lphin, Kate, kaffeine, amarok, k3b... take over minutes to load.
Sorry but i don't completly know what causes this, it some times happens when I have been playing multiple small videos with Kaffeine.
I am experimenting the problem right now, today I have had KDE all day working since 8:00 am, to 1:20 am (many hours), just using boinc-client, kget, amule, and 
Ares emulated with wine. All applications are pasive, processing and downloading. When i have came from work, i have tested a downloaded video, and following I 
have found that multiple KDE applications take minutes 
for launch, some of them may be never start (kaffeine for example).
I have seen this problem more times before, in other installations of Debian lenny + KDE, but in this same computer.
I have passed a memtest86+ without finding error in RAM.
It is possible this bug to have relationship with #461636 and #405965 bugs.
If i run 'ps aux | grep "appname"' i can see the program in execution:

rafael@rafadeb:~$ ps aux | grep amarok
rafael    4937  0.0  0.9  23012  9996 ?        S    01:56   0:00 amarok

rafael   31796  0.0  1.0  30248 10744 ?        S    01:27   0:00 kaffeine
rafael   31797  0.0  0.0      0     0 ?        Z    01:27   0:00 [kaffeine] <defunct>

You can see kaffeine, but i closed it before. Interesting..

I try to kill kaffeine (main possible cause):

rafael@rafadeb:~$ kill 28346
rafael@rafadeb:~$ ps aux | grep kaffeine
rafael    5922  0.0  0.0   3888   748 pts/2    R+   02:01   0:00 grep kaffeine

Now it is killed.

But problem persists:
I run again kaffeine and d3lphin, but after one minute they are not launched.
I see 'ps aux' again:

rafael@rafadeb:~$ ps aux | grep kaffeine
rafael    6311  0.4  1.0  30248 10740 pts/2    S+   02:03   0:00 kaffeine
rafael    6312  1.8  1.4  36976 14732 pts/2    S+   02:03   0:00 kaffeine
rafael    6379  0.0  0.0   3888   748 pts/3    R+   02:03   0:00 grep kaffeine
rafael@rafadeb:~$ ps aux | grep d3lphin
rafael    6154  0.3  1.4  30528 14984 ?        S    02:02   0:00 d3lphin
rafael    6285  0.7  1.4  30528 14980 ?        S    02:03   0:00 d3lphin
rafael    6405  0.0  0.0   3884   748 pts/3    R+   02:03   0:00 grep d3lphin
rafael   28260  0.0  1.9  32088 19748 ?        S    Mar28   0:01 d3lphin

They continue without launch after two munites.
A few seconds later d3lphin appears, it has been launched.
Around 15 seconds later other d3lphin appears (may be I started two d3lphins?).
Around 10-15 seconds later, kaffeine also appears.
They have taked around two minutes for launch.
Lets see now ps aux output:

rafael@rafadeb:~$ ps aux | grep d3lphin
rafael    6154  0.1  1.7  31436 18500 ?        S    02:02   0:00 d3lphin
rafael    6285  0.1  1.7  31480 18488 ?        S    02:03   0:00 d3lphin
rafael    7375  0.0  0.0   3884   748 pts/3    R+   02:09   0:00 grep d3lphin
rafael   28260  0.0  1.9  32088 19748 ?        S    Mar28   0:01 d3lphin
rafael@rafadeb:~$ ps aux | grep kaffeine
rafael    6312  0.1  1.8  39960 19220 pts/2    S    02:03   0:00 kaffeine
rafael    7383  0.0  0.0   3884   748 pts/3    R+   02:09   0:00 grep kaffeine

If you need more information, tell me.
Do you think that kaffeine could be the cause of all this?
See that in the first 'ps aux | grep kaffeine' execution, it seems to be locked or frozen, because i previously closed it, but it still appears in ps aux.
In addiction i have said that other times this started playing small videos with kaffeine. Interesting..

Sorry for this BIG report, you must be tired for reading, i hope for it to be useful. THANKS FOR YOUR WORK.
