[Qt-creator] Segfault during opening ui file

[Adrian Łubik]

Hi!
I've just installed the newest linux x86_64 snapshot and when I loaded
my project file, I opened main.cpp file by choosing it from the project's
files list, then I clicked on the .ui file and QtCreator simply crashed.
If I open the project and load the .ui file first, then QtCreator doesn't
crash.

I'm attaching the gdb output with backtrace.
