QtCreator has segmentation fault on Ubuntu 12.04 64 bit

I have a laptop with dual boot (Ubuntu 14.04 and 12.04 64 bit). In 14.04 I have no problems, but in 12.04 (kernel 3.8.0-44-generic) I installed qtcreator from the standard repository but it does not start. It quits with a segmentation fault.
The first lines from the backtrace output of gdb is:
