Ok, I wasn't specific enough. Sorry about that.
What I meant with "doesn't work" is: it doesn't load the symbols.
I have now tried "gdb /usr/lib/debug/usr/bin/kmail <pid>", and this gives me
the symbols for the main binary (and if pwd is ok or I add "-d <path>" to
the cmdline, it even shows the source code, so that's fine, too), but for
all the shared libraries, I'm still stuck.
add-symbol-file wants an address (where would I get this?); plain "symbol-
file" crashes gdb (and in any case: wouldn't this *replace* the symbol table
instead of add to it?)
cheers
