Tried id-utils packeage on my Ubuntu Gutsy,

$  mkid -o ~/mkid.ID .

it crashed with core.
Segmentation fault (core dumped)
However , no core appeared in directory where it was started.

$  ls -la core
ls: core: No such file or directory

under ubuntu core placed in /var/crash/

$ ls -la /var/crash/
drwxrwxrwt  2 root root    4096 2008-03-26 22:16 .
drwxr-xr-x 16 root root    4096 2007-10-21 01:49 ..

"/var/crash/_usr_bin_mkid.1000.crash" is not a core dump: File format not recognized
(gdb)

No way to debug packaged app's coredumps in ubuntu?

Not so, this is solution:

$ head -78 /var/crash/_usr_bin_mkid.1000.crash 
....77 lines with output ...
CoreDump: base64

And this:
https://wiki.ubuntu.com/DebuggingProgramCrash
page given me info on installing symbols;

then:

rtg@kubic-roman:~$ apport-unpack /var/crash/_usr_bin_mkid.1000.crash  ~/mkid_crash
rtg@kubic-roman:~$ ls -la /home/rtg/mkid_crash/

Yupp, not a much info.

Thats way I downloaded and installed it from sources (tar.gz from launchpad + patch + configure + make way).


uppps... this version crashes without core, even in crash :(
Finally, still searching for a way to obtain cores that were crashed.

tryied to edit:etc/security/limits.conf
uncommented core word containing line and tried to relogin:
and go to gdb again.

In gdb opened file as above, and seen

(gdb) where
