Pyside should at least the standard -dbg packages with the striped
symbols so gdb backtraces make sense. 

It would be nice to have everything for python3-dbg because it's a
pain to build debug packages when you need them. Esspecially when more
packages start not shiping them. But if the size is preventing that
for PySide then there isn't much to do there.

Problem is that recompiling pyside might not show the bug anymore
since the toolchain and build dependencies will have changed. Makes it
real hard to debug memory/stack corruption bugs.


Last building debug packages according to README.source does not work:

dpkg-source: error: syntax error in pyside-1.2.1/debian/control at line 383: duplicate field Package found

There is an empty line missing before "Package: python-pyside-dbg".
Either debian/control.in needs to end in an empty line or
debian/control.dbg-packages needs to start with one.
