the problem appeared in May after one upgrade.
Skype starts normally, but it doesn't change status of any of contacts.
Only Skype test call appears green -- but if I try to make test call it immediately fails...
I had Skype problem in OpenSuse 11.4 after one upgrade, but it was fixed in later upgrades. This issue doesn't seem to be fixed in any later software upgrades.
I noticed that some had problem after kernel upgrade - but I couldn't work it out in this case.
Any hints or ideas where to start?

Kernel version:
3.7.10-1.16-desktop #1 SMP PREEMPT Fri May 31 20:21:23 UTC 2013 (97c14ba) x86_64 x86_64 x86_64 GNU/Linux

KDE: kd4ease4-runtime 4.10.3-1.30.9

Thanks for your time.
