Is your project compiled with optimization turned on (i.e. `-O' or `-O2')?
Then the problem is not with GTK+, but rather with optimization producing
weird from the point of view of the debugger.  Some variables can be
optimized away, for instance, some initializations postponed until really
needed etc.  Try `info gcc' for more information.

So, just do `make -s clean; make -s CFLAGS="-g"'.

Hope this helps,
