Niceee

I will briefly explain how we get debug symbols packages installed:

- From the incomplete backtrace, we get the path of the .so libraries
with missing debug information.
(ex. "/usr/lib64/libQtCore.so.4")
- Using that path we get which packaged installed it
(ex. "libqt4")
- Now we check which package contains the debug symbols of the
previously fetched packagename
(ex. "libqt4-debuginfo" contains the debuginformation for "libqt4")
- Those packages get installed
- The backtrace is regenerated. (and hopefully complete now :) )

So, from a "package management" PoV we need to:
- Check which package ("A") contains a file
- Check the debug info package ("B") for the package "A"
- Install the package "B"

It is usually done this way. May be you can think of a better workflow
to install the missing debug symbols package; may be using some other
functions we can bypass the step 2. (so it will be: fetching the
debuginfo packagename from the library file path)

Happy holidays for you too.
Thanks for all your work, and have a nice and productive 2010 ;)
