[Bug breakpoints/19598] GDB breakpoint locks up Ubuntu UI, requiring reboot

--- Comment #10 from Dave Nadler <drn at nadler dot com> ---
OK, I managed to run the application from a non-GUI window with GDB, and found:
- when GDB breaks, the GUI is locked up, and
- if I "continue" in GDB, the GUI resumes normal operation

Leaves the question:

1) Most important: How can I prevent what-ever lockup is occurring on a GDB
breakpoint? This is really impeding work on this particular project;  its
enormously easier and more productive to work in Eclipse than with raw GDB...

2) Why did debugging with this exact breakpoint work a few months ago? There's
been to my knowledge no change in the application structure (for example grab
functions etc)...

Thanks again for the help,
Best Regards, Dave
