Thanks for the report. Such reports usually help to identify the
problem.

It looks like it, see http://sourceware.org/bugzilla/show_bug.cgi?id=10886.
That basically destroys Creator's ability to load the debugging helpers.

Unfortunately, even switching off the debugging helper does not help due
to another bug, see http://sourceware.org/bugzilla/show_bug.cgi?id=10884,
that causes gdb 7.0 to crash for C++ object containing bitfields, which
nicely "covers" the classes most interesting for Qt development, most
notably QObject and the Qt containers.

Right now it seems like the first bug has been around for a while, but
got more prominent in 7.0. The second one seems to be new in gdb 7.0.

I am not sure what a user friendly solution could look like given the
circumstances...
