kded4 process grows on memory usage

[alfabravoteam]

I've installed Kubuntu 11.04 beta updating from a previous kubuntu (which was just installed from a 10.10 standard ubuntu, installing kubuntu-desktop and uninstalling all the gnome stuff).
This computer is a HP dv6810 laptop, 3 yr old with an old battery that barely charges. Hence, I guessed this was related to the same thing as gnome's battery-indicator problem eating memory... and I removed it system tray. No good. Disabled Stagi and nepomuk as well... the 100% processor is no more (heh) but this problem still appears.
Now I'm testing with the whole system tray gone (maybe notifications...) but it looks like it grows as well.

The ubuntu-bug capture I'm sending was generated after an hour of use. The screenshots relate to previous tests (the last was from last night and today morning). Hopefully it will help you on catching the leak.

Letting the laptop on, with a firefox, a google chrome and a Dolphin window open... about 12 hours later it shows as seen in the screenshot.

Memory: 2.4GB... Shared memory: 14,926K

Killed the kded4 process and wireless was gone.

Then I ran kded4 --check and this was the output:

alfabravo@alfabravoTiger:~$ kded4 --check

In the end, wireless came back to life as the kded4 process restarted again with "healthy" 23MB in RAM.

we'll need a memory profile log of this...

killall kde4
valgrind --log-file=kded4.memcheck --leak-check=full --show-possibly-lost=no --show-reachable=no --undef-value-errors=no kded4

then let it leak a bit, and finally run hit Ctrl+c, after a while it will terminate and a log file named kded4.memcheck will be in your current directory, please compress this (e.g. xz -9 kded4.memcheck) and attach the compressed version to this bug

TIA
