The application I was debugging was akgregator, so:

akregator --version
Qt: 3.3.4
KDE: 3.4.92 (beta2, >= 20051010)
Akregator: 1.2

and

gcc -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ./configure  : (reconfigured) ./configure 
--enable-languages=c,c++,fortran,java,objc --no-create --no-recursion
Thread model: posix
gcc version 4.1.0 20051018 (experimental)

Cheers

Kevin
