Hi František Zatloukal, thanks for reporting back. Looking at your terminal output, it seems that you may be encountering a separate issue as there is currently a known SIGSEGV crash with software-center in Natty (bug 259219).
Please try launching software center from the terminal as shown: LD_PRELOAD=/usr/lib/libstdc++.so.6 software-center Software Center should start normally. After this, you can quit Software Center and it should launch normally (from the launcher, etc.) after that. If this doesn't solve the problem, then this is a different issue. Please report back here and we will try to help. Thanks!
