Closing Yast something segfaults?

Hi everybody.
When I am closing yast, from time to time I get this error. Although something segfaults the system seems to behave normally and I do not experience other issues…it seams. The error comes up in a small separate window. Yast stays operative.
Should I be worried about something? What is the system complaining about actually? Although this happens quite often, it does not happen always.

System is: 11.1 with
Linux linux-xu0v 2.6.27.45-0.1-default #1 SMP 2010-02-22 16:49:47 +0100 x86_64 x86_64 x86_64 GNU/Linux
and KDE 3.5.10 (r87)
Yast: 2.17.69-0.1.1-x86_64

BUMP!

Same error here, with recent vanilla install of 11.1-i586 (not 64)

“YaST got signal 11 at YCP file /usr/share/YaST2/clients/sw_single.ycp:587”

every time I close yast module

Hi, I solved up to now the issue because I reinstalled the system from the scratch in i586. I did not re-experience this. My doubt is however that it has to do with the mixed kde3-4 setup of 11.1. Which kde version do you use, 3 or 4? and if components of both (probably like me you are doing this to workaround the bluetooth issue and some other things) which version of them.
