Can't resist posting my own tweaked command:

for ld in $( dpkg -L libqt4-debug | grep '\.debug$' ); do
l=${ld%.debug}; sudo objcopy -R .gnu_debuglink --add-gnu-debuglink=$ld
$l; done

[Bug 128538] Re: Qt4/gdb: Cannot step into Qt4 functions

[Sergey Tachenov]

Looketh like .gnu_debuglink sections of the libraries are screwed up for
whatever reason--they are pointing to the libraries themselves rather
than to the libQt*.debug files. Running as root something like:

cd /usr/lib
for i in libQt*.4.3.2; do objcopy -R .gnu_debuglink $i  objcopy 
--add-gnu-debuglink=$i.debug $i; done

seemeth to help.

The funny thing is, libQt*.debug files also have .gnu_debuglink
sections and they are pointing recursively to the file itself too:
