Sorry for my long silence, I finally found a workaround for me, but I'd really 
like to have it fixed in a more definitive manner. Now that I got some free 
time again, here are some additional details.

First, everything is fine with a localy build dia, so the problems comes from 
the mdk package. It is uneasy however to prevent binaries from being stripped 
when building a package, the usual way is to produce a debug packages, with 
symbols exported into additional files. But it seems this is difficult to use 
multiple symbol files with gdb:

[guillaume@makhno presentation]$ gdb --symbol=/usr/lib/debug/usr/bin/dia.debug 
dia
Here is the output:

(gdb) r --export-to-format=eps-builtin *.dia

Does this help in any way ?
