Just a wild guess.
GDB checks libraries loaded. So depending on the info found on qt libs 
that may take time.

Try 
http://wiki.lazarus.freepascal.org/GDB_Debugger_Tips#internal-error:_clear_dangling_display_expressions
set the field "DisableLoadSymbolsForLibraries" to "True"

Or check in options/debugger/event log what is logged.  Disable "Module"
