It looks like there are some problems in coredumpctl with matching entries of
the list provided by 'coredumpctl list'.

My listing here:
TIME                            PID   UID   GID SIG PRESENT EXE
Wed 2014-09-03 12:54:03 CEST   6650  1000   500   6 * /usr/bin/kglobalaccel5

Now I'd like to handle the last entry of the list (PID 6654).
coredumpctl(5) says I should be able to use PID=6654 as match:

% coredumpctl info PID=6654
No coredumps found.

While COREDUMP_PID (suggested on IRC by dreisner) works:
% coredumpctl info COREDUMP_PID=6654
           PID: 6654 (kglobalaccel5)
           UID: 1000 (elias)
           GID: 500 (elias)
        Signal: 6 (ABRT)
     Timestamp: Wed 2014-09-03 14:34:31 CEST (27min ago)
  Command Line: /usr/bin/kglobalaccel5
    Executable: /usr/bin/kglobalaccel5
 Control Group: /user.slice/user-1000.slice/user at 1000.service/dbus.service
          Unit: user at 1000.service
         Slice: user-1000.slice
     Owner UID: 1000 (elias)
       Boot ID: ff9eec4b3e024935b724067f6b4305c4
    Machine ID: c7a150de6cd901b63a1317770000000b
      Hostname: moria
      Coredump:
/var/lib/systemd/coredump/core.kglobalaccel5.1000.ff9eec4b3e024935b724067f6b4305c4.6654.1409747671000000.xz
       Message: Process 6654 (kglobalaccel5) of user 1000 dumped core.


Then again, using exactly this matching criteria for 'coredumpctl gdb' doesn't
work:
% coredumpctl gdb COREDUMP_PID=6654 
No match found.


So it looks like there are at least 2 issues:
- the manpage is not consistent with the implementation
- the implementation uses tool-specific (info, gdb, …) matching implementations

Running current git master of systemd.
