Hi,
  This isn't gnome-terminal (happens in other terminals).

But I also, don't think it's actually a bug; I think ps -A is using /proc/pid/comm to get the unchangable task name, the
kernel docs (Documentation/filesystems/proc.txt) state:

3.6 /proc/<pid>/comm & /proc/<pid>/task/<tid>/comm
--------------------------------------------------------
These files provide a method to access a tasks comm value. It also allows for
a task to set its own or one of its thread siblings comm value. The comm value
is limited in size compared to the cmdline value, so writing anything longer
then the kernel's TASK_COMM_LEN (currently 16 chars) will result in a truncated
comm value.

So, that's what the kernel provides, so I don't think that's a bug.
(You might decide it is a bug, in which case it seems to be the kernel).
