gdb & gtk+: Cannot find new threads: generic error

[knocte <knocte gmail com>]

Hello. I have a wierd gdb problem which is only reproducible with some
gtk programs but not all of them.

For example, gedit works perfectly:

knocte111 linux-jsnn:~> gdb gedit

(gdb) run
Starting program: /usr/bin/gedit
[Thread debugging using libthread_db enabled]
[New Thread 0xb35d9b90 (LWP 5765)]

After that, I see the new window of gedit appearing.

However, this doesn't work for gtk-demo:

knocte111 linux-jsnn:~> gdb gtk-demo

Error while reading shared library symbols:
Cannot find new threads: generic error
Cannot find new threads: generic error
(gdb) quit
The program is running.  Quit anyway (and kill it)? (y or n) y



Any ideas why this happens?

Thanks very much,
