the same happens with gtk-2.10 and pygtk-2.10 (unstable)
I am trying to trace down a x11 error. Could you also tell me how to use the
--sync flag without dbg version of gtk?
The last lines of strace are:
LD_LIBRARY_PATH=/usr/lib/debug/usr/lib strace /usr/bin/python2.4 -c "import gtk"
open("/usr/lib/libpng12.so.0", O_RDONLY) = 5
read(5, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\2406\0"..., 512) = 512
fstat64(5, {st_mode=S_IFREG|0644, st_size=137760, ...}) = 0
mmap2(NULL, 140716, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 5, 0) =

MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 5, 0x21) = 0xb7226000
close(5) = 0
so it might be an issue for libpng12, too.

There is nothing special to do. Just install the package, and the
debugging symbols will become available when using gdb.
