No need to learn GDB, I suggest you use KDevelop, debugging there works. Read 
http://techbase.kde.org/Getting_Started/Set_up_KDE_4_for_development#KDevelop 
to set it up correctly.

The problem using a KDE 3 application (kdbg) to debug a KDE 4 application 
(konqueror) is that the environment variables for one of those will always be 
wrong, causing errors like you descibe.
Using kdbg 'which konqueror', the environment variables for kdbg are wrong.
Using start3app, the environment variables for konqueror are wrong.

KDevelop can work around the problem by setting environment variables when 
running/debugging an application (see the techbase article)

Hope this helps,
Thomas
