[Pygui] Problem with PyGUI on Ubuntu 11.10 (Greg Ewing)

[Shankar Giri Venkita Giri]

On further experimentation, libgirepository-1.0.so.1.0.0 is the library that causes the segfault. I rebuilt this library without debugging symbols and even stripped it so that it closely matches the original file packaged with Ubuntu 11.10 in size (there is a slight difference though). And the examples worked without a hitch. Something in the original ubuntu binary is causing a segfault. Since the original binaries are stripped, there is no way to know which version of gcc was used to compile it. Maybe a compiler bug (original binaries may have been compiled by a different version compared to the gcc packaged).
