Hello,
the source file 'fnewqsodefvalues.pas' is missing in source package. Is that a old/new file without relevance? I have deleted the loading of this file in cqrlog.lpi.
After starting the project breaks at line 865 in LCLProc 
<code>
procedure RaiseGDBException(const Msg: string);
begin
  debugln(rsERRORInLCL, Msg);
  // creates an exception, that gdb catches:
  debugln(rsCreatingGdbCatchableError);
  DumpStack;
  if (length(Msg) div (length(Msg) div 10000))=0 then ;
end;                                                   
</code>
Normally, the debugger stops when it catch in error. Here, the program stops at above line. 
If I run it from console, it stops with this error every time the 'Edit QSO' window is called:
<code>

Which version of Lazarus/Freepascal do you use? I use Lazarus 1.1 (the CodeTyphon Package) with LMDE.
