Bug Description

I was just searching for qtcreator and other qt packages(also kde). I have installed nothing. Software center crashed and with it apport catched a SIGSEGV in unity-2d

A look in the kern.log shows also:

Mar 17 18:47:51 user-virtual-machine kernel: [ 1286.641161] unity-2d-shell[1709]: segfault at 280000000 ip 00007f4090bc8dd2 sp 00007fff4e508ea0 error 4 in libQtDeclarative.so.4.8.0[7f409096f000+387000]

So you can see that libQtDeclarative.so.4.8.0 is problematic.
