Salut, 
 
here my output,  
 
bash-2.05b$ cd /opt/gambas/gambas/app/gambas 
 
bash-2.05b$ gdb gbx

Breakpoint 1, TRACE_init () at gbx_trace.c:234

(gdb) break /opt/gambas/gambas/src/lib/qt/ext/CTableView.cpp:1074 
No source file named /opt/gambas/gambas/src/lib/qt/ext/CTableView.cpp. 
 
(gdb) break CTableView.cpp:1074 
No source file named CTableView.cpp. 
 
I had a look to qt/ext and I'm saw it was compiled with -g  
So it has to be something else, I ignore ? 
 
To you have an easier call, which work on your box. Just for testing ? 
 
Amicalment
